BASIC CONCEPTS

Machine axes X-, and Z- axis and their respective positive and negative displacement directions are shown on the above schematic diagram. As you can see, when work piece zero reference point is located on work piece end (most common case), the positive direction is outside the work piece, while the negative direction is on the work piece area to be machined (inside the work piece). Commonly, you will operate in the quadrant defined by X+ and Z-. The machine will enter only in X- area for facing operations. C-axis would be used to swivel the head in order to position the work piece for drilling operations using a powered tool. C+ is in clockwise direction and C- is counter clockwise direction. .


Other axes that could be encountered when programming the machine are

F: feed axis (related to slides) to be programmed when in operation. In millimetres x per revolution when the head is rotating (turning) For example: G99 F0.3 this means “03 millimetres per revolution”. In millimetres per minute when the head is stopped (MC). For example: G98 F80 this means “80 millimetres per minute” T: is turret rotation. R: is radius programming. S: are head revolutions (cutting speed) this letter is always related to heads. G50 S1000 Rpm limit. G97 S1000 fixed rpm (for tapping and drilling). G96 S200 cutting speed (m/min) for all turning operations.

Cutting speed formula:

Vc= Cutting speed D= Part standard diameter n= Rpm limit.

C: Chamfer programming (Standard type). A: Angle programming (Standard type). ,C: Chamfer programming (MC type). ,A: Angle programming (MC type).

Tool offset The offset value is the protruding length of tool end from the zero reference of turret disc. The required offset values must be entered each time tool position is changed with respect to the aforementioned position; if tool position is not changed, entering a offset value will not be necessary as these values are stored in the memory.

Entering tool offset values There are two ways for entering tool correction values. 1st.) Supplied with presetter. For machines with presetter, place the presetter in position and preset the tool. 2nd.) supplied without presetter. For machines without presetter, turn the work piece and retract the tool without moving it out the axis. Then measure the work piece and enter the readings in the geometry table. To enter a value, go to the geometry table (offset value), enter the required value and press the intermediate key; by this way the control unit will calculate the offset value.

Workpiece zero reference point Workpiece zero is the work piece protruding length from main chuck face.

It can be also placed in other location, even though it is advised not to do it, as following up and verifying the program would much more difficult and you should continuously calculate the difference between this position and work piece end. We advise you to enter work piece zero at the beginning of the program. For Example: G10P0X0.Z-120.

In this manual we will always refer to G codes type A. Comment: These are notes included in the program. These notes are totally optional, and it is up to the programmer to enter them or not. These notes will be always placed in brackets () in order to prevent the program reading them. T101 Here is shown that the tool to be used is in position 1 and a offset value of 01 is applied. T0101 could be also entered, as the four mandatory characters are present, however, the first zero is optional. Head rotation direction: M3 head rotation direction forward M4 head rotation direction reverse G0 X150 Z150 Note that tool retraction in this example is to 150 mm on X+ and 150 mm on Z+ from work piece zero, and not from chuck face, as no order for changing the position is given to work piece zero, which in this example is maintained in the previous position. Line number (N10, N20...) Line numbers are optional, and can be either entered or not. G0 G40 G99 X45. Z0. M8 As you can see, G codes are first placed and then X, Z and M codes.

P Cutting depth on X-axis (Micron). Q Step over on Z-axis for next pass (Micron). F Instantaneous feed (mm/revolution).

The subprogram is called by means of command P followed by a number. This number consists of four or more characters. If the number consists of four characters, it indicates the identification number of subprogram to be called. If the number consists of more than four characters, the first four characters, from right to left, indicate the identification number of subprogram to be called. Next characters indicate the number of repetitions of subprogram to be called.

As described above, a subprogram or part of a subprogram is repeatedly called by means of a command P followed by several numerical characters. In this example, the subprogram is repeatedly called by means of “P41001”. This command consists of three parts: “P” calling a subprogram. “4” number of subprogram repetitions. “1001” number consisting of four characters and directly referring to the subprogram.

The maximum number of repetitions for a subprogram in a single call is 9999.

C-Axis and powered tooling

This section describes the procedures used to program MC type machines controlled by the C-axis.

1- Stop the spindle by entering the command M5 before entering command M45

2- Before entering command M44, the powered tool must be stopped by entering command M5.

3- M17 brake on command is optional depending on the diameter of the tool being used the following examples use the brake command.

C-axis would be used to swivel the head in order to position the work piece for drilling operations using a powered tool. C+ is in clockwise direction and C- is counter clockwise direction.

Polar coordinate interpolation Polar coordinate interpolation is used when it is desired to perform milling operations on the face of the work piece, which require synchronous movement of the spindle and live tooling mounted on the turret. When polar coordinate interpolation is commanded by the G112, the control interprets several pieces of data to determine the direction and speed at which the axes must be moved to reach the commanded end point.


The drawing below shows the coordinate system used with polar coordinate interpolation. The programmed end points are laid out as coordinates on this plane. Note the signs for X and C. The following program examples illustrate the use of this system.

1. The following G codes may be used when G112 is active: G1, G2, G3, G40, G41, G42, G65, and G98.

2. G0 positioning is not allowed when G112 or G12.1 is active. 3. When using G2 or G3, the arc radius is specified using the R word. 4. M45 C axis mode must be active before commanding polar coordinate

interpolation. 5. The spindle should be oriented to C0 degrees before commanding polar

coordinate interpolation. 6. If machining in the X axis only, do not activate polar coordinate interpolation. 7. The unit of command for the C axis, when polar coordinate interpolation is

used, is MM or inches, not degrees. 8. When using cutter compensation during polar coordinate interpolation, the

same basic TNRC rules apply as with normal lathe programming. However, the following rules must also be observed:- The tool radius and the quadrant must be loaded into the geometry offset file. For polar coordinate interpolation, the X tool offset represents the centre of the cutter and the tool tip location (Quadrant) will be set to 9.

9. The TNRC start up block (G41 or G42 line) must be programmed after the

polar coordinate interpolation command (G112 line) has been activated. For polar coordinate interpolation, the X axis move must be equal to at least two times the tool radius entered in the tool offset file. Program the G40 (TNRC cancel) command before the block containing the G113 or G13.1 (cancel polar coordinate interpolation).

10. Program restart and block restart are not allowed when G112 is active.


11. Specify the feedrate as millimetres per minute.

12. X values are diameters and C values are radii

Tool nose radius compensation and circular interpolation used with G112 polar coordinate interpolation The drawings below show the combination of tool nose radius and circular interpolation codes used with polar coordinate interpolation. The shaded area in each drawing represents the finished part contour.
