What's New?

ew Functionalities

chnological Results

Technological Results supplies information on the features included in a body. This information can

be used by downstream applications such as Prismatic Machining, for instance, or downstream useralyze block of concurrent engineering

A new function called Tooling Structure Analysis produces a report informing you of the interactionbetween the various parts of a tooling structure - which elements have an impact on a given elemeand which elements are affected by a given element.

lling in Context

A part interface has been added to allow you to safely modify a single block in a tooling structure eit is impacted by another block

tributed Drill Component

A new command that allows you to drill components by one or more drilling components that havestandard or customized names.

tivate/Deactivate Tooling component

Standard components and any associated holes they may have can now be deactivated and/orreactivated.

nhanced Functionalities

itting Surfaces

Splitting surfaces are automatically optimized to reduce memory usage, wherever possible, for use

all components other than user components. A specific syntax can be used with user components fosimilar result.

mponent positioning in axis mode

This is a new mode for inserting components. It depends on a BaseAxisSystem that is defined in thcomponent itself. The component position is defined by the guided selection of one or two axes andresults in the creation of angle constraints.

ustomizing Settings

lling AssociationsThis setting defines associations between drilling bodies and target bodies of the components to driusing customized names (if required).

e-selection codes

Pre-selection codes can be added to the end of drilling body names to define, in one shot, thecomponents they are to drill.

sembly of bodies as opposed to addition and removal

Pads, pockets, drillholes and tapholes are now assembled by default. A check box allows you to addremove material rather than assembling it.

Adding Components

These tasks show you how to select and position standard components.

The dialog box and the operating mode are the same for all components (whether in standard mode or guided mode).

Components can be added to an existing mold or to an empty CATProduct

There are several restrictions concerning the manipulation (notably when copying, pasting, deleting, dragging and dropping) o

components and drilled CATParts. Click here for more information.

Adding a component to an existing moldCreate a mold as explained in Creating a User-defined Mold Base.

You will:

q choose a first reference, (go directly to Positioning a component if a reference is already in use)

q position the component,

q create and manage several instances,

q drill holes,

q set the parameters values,

q define positioning constraints,

q activate a rule,

q Create a component in an empty CATProduct.

Choosing a first reference

1 . Click on one of the component icons (here Add LeaderPin). The Define LeaderPin dialog box is displayed.



76/306

2 . Press the catalog icon to access the catalog browser. Select the catalog name, then the component type and the

component reference: double-click on the required label to go to the next step, the last one reverting to the main dialo

with its Config fields updated with the Supplier name and the Reference of the component.



77/306



78/306

The Config area is a reminder of the reference of the component. It can not be edited. You can only select another reference

component of the same type, using the catalog icon , or select another reference from a file, using the File Open icon

You could use one of your own components instead of one from a catalog:

Press the F il e O p e n icon in the dialog box and browse your directories to that containing your component. Select thecomponent. You are then asked to position it, as in step 3 below. The Config fields are not updated.

Special case of the screws (CapScrew, CountersunkScrew, LockingScrew)

The operating mode is the same, but is enhanced by a smart filter in the catalog.

If the Dril l to field is already defined, the distance between the active preview location and the To plate is computed, i.e. aminimum and a maximum length are set for the screw.



79/306

The minimum and maximum lengths are set as filters for the Catalog browser dialog box, applied to the L parameter of the sc

so that only references with appropriate lengths are proposed.



80/306

(we have resized the dialog box to display all proposed references).



81/306

You can further refine the selection filter by using the Specifics tab :

q S u n k He a d is active by default and you can enter the value that you want the head to be sunk into the plate by (0 mm mthat the head is flush with the plate surface),

q Check D i a m e t e r to select a diameter for the screw (to refine selection filtering):

r The first value is the diameter of the screw,

r The second value is the coefficient that defines the distance at which the tip of the screw will be sunk into the To plate

(drilling destination plate).

If, for instance, we wanted to drill from clamping plate to cavity plate, we might obtain the following selection to choose from



82/306

but if we added that we wanted a screw with a diameter of 10mm, the selection to choose from would be much shorter:

If the Dril l to field is not defined, or if you clear the filter field,

you can then select any screw from the complete list.



83/306



84/306

Positioning the component

q Standard components are "smart" - they know where they should be in the specification tree when they are created. In socases (e.g. angle pin, insert, fixing components, guiding components, locating components and spring), it is not automaticposition of the components is determined by the information you give in the Dri l l f ro m field. This allows the positioning

constraint between the component and any plate.

q In the T o o ls , O p t i o n s menu, then Me c h a n i c a l D e s ig n , Mo l d T o o lin g D e s i g n customization dialog box, you can definedefault plate positioningfor the components. That way, when you create a new component of a customized type, it will be

positioned automatically on the correct face of the correct plate, without previous picking.

q In t h e To o ls / O p t io n s / Me c h a n ic a l D e s ig n / S k e t c h e r , activate the P o s i t io n s k e t c h p l a n e p a r a lle l t o s c r e e n option, G r id S n a p t o P o in t option if needed.

3 . Select a face of a plate. The sketcher is displayed, with a manipulator to position the component. The Dri l l f ro m field

updated automatically with the name of the plate you have selected.

The grid is displayed. The Ac t iv e I n s t a n c e O r ig i n is updated. You can now define the coordinates of the newcomponents by picking either:

q a 2D point on the face,

q a 2D point outside the face that will automatically be projected onto the face,

q a 2D point sketch on the face,

q a 2D point sketch outside the face that will automatically be projected onto the face,

q a 3D point on the face,

q a 3D point outside the face that will automatically be projected onto the face, or

q an axis, an edge, or a line that will automatically intersect with the selected face.



85/306


86/306

Standard mold bases include 3D points that are identified as being for the location of components.

When the component is created on a 3D point you can change its orientation by picking a 3D line, an edge or the axis of anotcomponent. If the selected axis is parallel, the position of the component is projected onto the intersection between the selectaxis and the component reference plane; if not, the orientation of the component is modified according to the selected axis.

Positioning the component in guided axis mode

This mode allows for the insertion of components. The component position is defined by the guided selection of one or two ax

In order to use it, you must define a BaseAxisSystem in a standard component. To do this, you must define one or more of thfollowing Boolean parameters:

q BaseAxisSystem_X_Select

q BaseAxisSystem_Y_Select

q BaseAxisSystem_Z_Select

The order in which the Boolean parameters are defined TRUE determines the order in which you will be asked to select the ax

Then save the component.

1 . Open file MoldProduct.CATProduct in the samples/PositionSlider directory.

2 . Click on the Add User Component icon .

3 . In the same directory, choose GuidedZX_Component.CATPart. A small x is displayed beside the cursor

indicating the position where the component is to be located. Click on a point or an edge vertex.

4 . A Z is displayed beside the cursor.

Choose an axis, edge or line to indicate the component's Z axis.

5 . An X is displayed beside the cursor.

87/306

Choose an axis, edge or line to indicate the component's X axis.

Positioning is now complete. Press OK to create the component.



88/306

Note that an angle constraint is created for each of the axes that you defined as is a coincidence/offset constraint for the posipoint.

Creating and managing several instances

IfS e v e r a l I n s t a n c e s p e r Re f e r e n c e is set to Ye s in the To o ls / O p t io n s/Me c h a n ic a l De s ig n / Mo l d To o l in g D e s i g n dialoall the instances of the component that you create will have the same reference:

Then logical computations will be the same for each instance.

We recommend not to activate S e v e r a l I n s t a n c e s p e r Re f e r e n c e for components to be split, each instance needs its own ssplitting result.

If this option is set to No, each instance of the component that you create will have its own reference:

The Ma n a g e A ll option defines whether you create just one instance of the component or several in one shot depending on wyou select to position the component. When this option is active:

q selecting a 2D point will effectively select all of the other 2D points in the mold and create an instance of the component oof them,

q selecting a 3D point will select all of the 3D points on the same face.

q the previews of all instances of the component are active (red) meaning that moving one component preview (or reversindirection) will move all the other instances of the component (or reverse their direction).

Please note that R e v e r s e D ir e c t i o n and rotation angle values are always applied to everything that is selected whether M a nAl l is active or not.



89/306

Ex: select LeaderPin4 with Manage All de-activated. Only one instance is created.

Ex: select LeaderPin4 with Manage All active. The four instances are created.



90/306

q Once several instances of a component have been created, Ma n a g e A ll defines whether your modifications apply to all orone instance.

Ex: The four instances were created with Ma n a g e A ll active. It was then de-activated. Only the instance created on the pointremains active.

q The active component is always red, the others are green.

S e v e r a l I n s t a n c e s p e r Re f e r e n c e allows you to create several instances of one reference component. If you deactivate thisoption, only one instance will be created per reference component.

This option overrides the same setting in To o l s / O p t io n and is only applied to the current creation.

Drilling holes and positioning

q For all components but screws, open holes are drilled.

When dealing with screws, the type of hole depends on your selection for the Dri l l f ro m and Dril l to locations:

r if only the Dri l l f ro m location is defined, either as a plate or a component, a standard hole is drilled,

r if only the Dril l to location is defined, either as a plate or a component, a tapped blind hole is drilled,

r if both areas are defined, either as a plate or a component for each one, the hole is standard in the element set as thef r o m location and a tapped blind hole in the element set as the Dril l to location.



91/306

Except when you are working on a support, by default, the Dri l l f ro m and Dril l to area are set to N o s e le c t i o n (no hole dril

you wish to define the holes associated to the component, first select the fields Dri l l f ro m or Dril l to in the dialog box, then

plate or a component in the graphic area to define the other reference plate.

q If you wish you can select the plate or component in the specification tree (expand the tree first and select the reference)

q When working with a support, selecting the plate updates automatically the Dri l l f ro m field with the name of that plate.

q All plates located between the two reference plates are drilled as well.

q For all pads and pockets created by Adding or Removing Material: pockets are removed whereas pads are added in the Dr

f r o m (plate or component) area.

The Be t w e e n Fr o m a n d To button has become available.

You can now select plates or other components found between the Dri l l f ro m element and the To element:

q select an element in the viewer to add it to the list of elements to be drilled,

q select an element in the dialog box list and push the D e le t e S e l e c t io n button to remove it from the list of elements to bedrilled.



92/306


93/306

R e v e r s e D i r e c t io n or W arrow is used to reverse the direction of the components.To change the orientation of only one component, edit the component after having created it.

The color of an associated hole is that of the element in which it is created. If you want to assign a specific color to some of thfaces in an associated hole, you must modify the color of the features included in the bodies named DrillHole/TapHole. For exif the DrillHole body of a component is composed of a blue feature hole and a red feature hole, the associated hole will have band red faces.

When inserting a component into a mold, you can reduce the time required to update your mold by adapting your session setGo to To o ls > O p t io n s > As s e m b ly D e s ig n > Ge n e r a l. Choose to have an A u t o m a t i c U p d a t e on the Ac t i v e l e v e l (as shownbelow).

This automatically updates all of the parts of the model that are on the same level as the one currently active and not the entmold (i.e. it updates the relevant part of the mold only and thus saves time).

For further information see the General chapter on Customizing in the Assembly Design User's Guide.

This opens the CATPart of the component in a new window, where you can edit it.

For example, we have changed the shaft angle of the LeaderPin in the new window, this change is taken into account in all the instanthe LeaderPin in the Product.

Activate/Deactivate LeaderPin Component

This is a toggle function, components that were already deactivated will be activated and active components will be deactivated and

displayed in visu mode in the tree.

One component or a group of components may be selected for activation/deactivation.

Deactivated components are:

q not visible in the viewer nor are their associated holes,

q ignored by the Explode Holes command,

We recommend that you do not use the ordinary D e l e t e function, since the associated holes would not be deleted.

Add New Instance

Enables you to add new instances of a given reference. The operating mode is similar to that ofAdding Components.

There are two important options to the creation of new instances:

q IfS e v e r a l I n s t a n c e s p e r R e f e r e n c e is not active, you will create an entirely new reference and instances of that reference,

q IfS e v e r a l I n s t a n c e s p e r R e f e r e n c e is active, you will create new instances of the original reference.



104/306

In this case ( S e v e r a l I n s t a n c e s p e r R e fe r e n c e is active), if the reference is a CATProduct with subparts, the new instances willbe created but new references will not be created for the subparts.

New instances will contain exactly the same subparts as the original.

This task explains the requirements for a user component. A user component is a component that does not belong to a supplier catalog. These componenmust be added to a user's catalog.

There are several restrictions concerning the manipulation (notably when copying, pasting, deleting, dragging and dropping) of components and drilledCATParts. Click here for more information.

The examples below are taken from WearPlate.CATPart which as been added to MyComponents.catalog found in the catalog directory in the samples

directory.

Structure of a componentTo obtain a good result when inserting user components in a Mold Tooling Design project, it is important to follow some rules detailed hereafter.

A Mold Tooling Design component can be a CATPart or a CATProduct, which may contain one or several CATPart that can be Mold Tooling Design compon

The name of the CATPart or of the CATProduct must be the name of the user component that is also used in the catalog (here W e a r P l a t e _ Z 1 5 W ).

A CATPart of a component is composed of:

Parametersq We recommend that the Z+ axis of the component be oriented upwards (towards the injection side).

q Some parameters that can be associated to one or several design tables. This is recommended if an object has several sets of parameters. The namethe design tables are free.

q The P a r t B o d y that contains the geometry of the component. It may consist of pads, sketches, technological results etc. The name of the P a r t B o d yfree.

q A body named B a s e B o d y that contains a point named B a s e to locate the component when it is inserted in the mold. In case of assembled componenCATProduct), the Base point of the first CATPart is taken into account for the location.

q If needed, a body with a name that starts with Dril lHole that contains the definition of the associated drilled holes that are removed in the elementsdefined through the Drill From/To function of the component panel.There may be several of these and we recommend that you insert as many as necessary for your machining strategy (to differentiate, for instance, thholes that were in the original part to machine and the holes that you wish to insert).

q If needed, a body with a name that starts with T a p H o l e that contains the definition of the associated threaded holes that are removed in the elemendefined through the Drill To function of the component panel (this element is the latest of the list).

q P a d s can be used to add material around a component. Give the body a name that begins with P a d , e.g.PadForContouring. We recommend that yochoose names that indicate the final purpose of the pad or pocket as there may be several in a user component.

q P o c k e t s can be used to remove material around a component. Give the body a name that begins with P o c k e t e.g.PocketForMilling. We recommend

you choose names that indicate the final purpose of the pad or pocket as there may be several in a user component.

Pads and pockets are only applied to the element defined in the D ri l lFrom field of the D e fin e C o m p o n e n t dialog box.

The Explode Holes command takes into account only Hole features defined in the bodies DrillHole, TapHole or CoolingBody. Other types of features areignored. Therefore, pockets, grooves, patterns, symmetries, translations, rotations, thicknesses,... that might be defined in those bodies are not processethe Explode Holes command and you should not define components with those features.

For more information, see the Explode Holes User Task.

3 . Create a slider.

Position the slider on the appropriate plate (usually the CorePlate, or eventually the CavityPlate)in your mold base and use the arrows to set it in place.

Note that the coordinates are displayed under the cursor as you move it.

4 . Align it with the slider Z axis either by selecting it on the model or by clicking on it in the tree

(S lid e r D ir e c t i o n . 1 ).

5 . Make any other adjustments you may wish and press OK.

The parameter named R e t r a c t i o n defines the length of retraction of the slider to avoid collision prob(elimination of undercut) during the ejection process.

In the V5 model of the slider, a line representing the needed axis for the An g le P in has been createdThe tilting angle (AP angle in the drawing below) of this line is modified when the parameter namedR e t r a c t i o n is modified.

The parameter named H defines the height of the slider.

When parameters H and/or R e t r a c t i o n are modified, the AP angle is modified but its value might noan exact value in degrees. Therefore, the value ofR e t r a c t i o n is re-computed to allow the rounding uAP angle. The R e t r a c t i o n field is updated accordingly.

This task will show you how to replace a component by another from the same reference catalog or from a different one

You need at least one component to replace (the first two steps below deal with that).

This function does not create a new reference for the subparts of the CATProduct component to replace. The new compocontains exactly the same subparts as the original.

1 . Open file Product1.CATProduct in the samples/DrillFrom directory, show the injection side and hide the ejection s

and the ejector system.

2 . Create three sleeves ( ) from the DME catalog, reference TD-28-120 anywhere on the clamping plate.

This task shows you how to split the cavity plate and the core plate with a surface.

Sprue bushing and other user components can also be split.

A splitting surface may be the core, cavity or any other appropriate surface.Splitting surfaces are automatically optimized to reduce memory usage, wherever possible, for use wall components other than user components. See the chapter on User Component Requirements for m

details on how to split user components.

When splitting a component, all bodies included in the component will be split. If there is a body thatdo not want to split, rename it with two underscores as a prefix (i.e. b o d y 1 becomes _ _ b o d y 1 ).

When the number of instances of the component is greater than 1, a dialog box informs you that thecomponent cannot be split.If you wish to have only one instance per reference, deactivate the S e v e r a l I n s t a n c e s p e r R e fe r e n

option in To o ls > O p t io n s > Mo ld T o o lin g De s ig n > Co m p o n e n t .

When ejectors, ejector pins, ejector flats, ejector sleeves and core pins go through a component thatsplit, their guided hole length will be maintained even though their overall length is shortened. Guidehole length is defined by the Offset Parting parameter.

1 . Open S p l i t . C A T P r o d u c t in the samples/Split directory.
