TINY CNC-SC Model



What is NC Milling Machine?

[2]

NC milling Machine is a Numerical Control Machine used in manufacturing

using Acryl, Wood, Aluminum or etc. NC milling machine can control high

accuracy manufacturing compare with other milling machine

NC milling machine can manufacture various shape using NX

Program manual

[12]



Program manual – code window

[13]

① Code window : CAD/CAM file is converted to G-CODE or NC-CODE.

Computer reads this NC-CODE and send to controller, then equipment

moves along NC-CODE. Code window read and shows that NC-CODE.

LINE : ‘LINE’ shows the current line

number of NC-CODE. If a user want to see

certain line, then click and put a certain line

number and ‘Enter’.



Program manual – run window

[14]

② Run window : This window control the start and stop of equipment



Program manual – run window cont.

[15]

: Equipment runs code from next line of selected line. Click

‘ 다음줄부터 실행’ and click ‘ 시작’ button then NC machine

will operate from next line of selected line

: Equipment runs line by line from selected line. Click ‘ 한줄씩 실행’

and click ‘ 시작’ button, then NC machine operate a line




[16]

: This button is used when the user want to start NC machine from certain

line

1. Select certain line that want to start and click ‘ 여기부터 실행’

and click ‘ 시작’ . Then a message window popped up. This window

shows coordinate values of previous step. Click ‘ 시작’ again, then

the axis of equipment moves to selected position. And click ‘ 시작’

once again, then the operation starts.




[17]

: This button starts the machine’s operation. Before start, zero adjustment

is needed

: This button stops the machine’s operation

: This button is used when the code get back to the first line

: Pause the machine while manufacturing process.

User always click this button when user want to stop

a machine moment




[18]

: This button represent ON/OFF switch between PC and NC. When the signal

is off, then red light and green light above the reset button flicker and

‘Emergency Mode Active’ message shows

: Inversely, when the signal is on, green light is on and ‘Emergency Mode Active’

message is disappear

: This button shows the window such as page 11. Basic window

: This button shows the window in 18 page. It is used to check x, y, z axis sensor.

When sensor operates, yellow lamp is turned on.




[19]



Program manual – jog mode window

[20]

③ Jog mode window : This window set velocity and user can move with constant

velocity or step using x, y, z key. Also this window is for relative

zero adjustment



Program manual – jog mode window cont.

[21]

• When user want to set a origin at certain point on the material, then click ‘Zero

X’, ‘Zero Y’, ‘Zero Z’. These button make stop point to program origin




[22]

: When green lamp is ON, jog mode operate. But

when lamp is OFF, jog mode is not operate. User

should check weather lamp is ON or OFF

: Each time user click ‘ 수동 조그방법‘ , lamps are turn

on with ‘ 연속’ or ‘ 단위’ . When lamps are on

‘ 연속’ - Tools move continuously with set velocity.

‘ 단위’ – Tools move exact distance that previously set.

Distance can designated at ‘ 단위 이송량‘ part




[23]

: When user set ‘ 연속’ at ‘ 수동 조그 방법’ , tool’s

velocity can control using ‘ 이송 비율’ .

100 % means tools move with their set velocity, and

50% means tools move with half velocity that they

set.



Program manual – Code trajectory window

[24]

④ Code trajectory and origin window of tool : User can control about tool path

trajectory from NC-CODE and origin of tool.



Program manual – Code trajectory window cont.

[25]

• This window shows NC-CODE’s trajectory. Green line represent tool’s manufacturing route.




[26]

: Click when the origin of program and origin of material isn’t match. This reproduce the manufacturing path.

: Absolute origin of NC machine. Normally, bottom left node is an origin of NC machine




[27]

: X axis origin of NC machine

: Y axis origin of NC machine

: User setting origin. It’s relative origin. If click this button, then axis moves to set origin. (User set origin at page 20)

* ‘X 축 원점’ + ‘Y 축 원점’ = ‘ 장비 원점’




[28]

: When you click this ‘ 공구 높이 셋팅’ button, then cutting edge is

moving down to the bed. If moving down tool meet height sensor, tool’s

moving stop. Then put a z axis value of tool to jog mode window for

setting the height of the tool

* But height setting should consider zero face from

CAM software. Refer the following table. Suppose

that material’s height and sensor’s height is 10 mm.

ZERO FACE Z axis height

TOP 10mm

MIDDLE 15mm

BOTTOM 20mm




[29]

When material processing, FEED(Velocity) value

is ‘ 설정속도’ . According to ‘ 증가’ and ‘ 감소’ ,

‘ 설정속도’ control the velocity referring the ‘

비율속도’

Ex) ‘ 설정속도’ = 450 mm / min and 100%.

If I increase 200%, then ‘ 비율속도’ will change to 900 mm / min and ‘ 현재속도 (current

velocity)’ is change to 900 mm / min.




[30]

: This represents manufacturing processing time

Materials

[32]

We have following materials

• NC machine

• 3 inch chuck

• Controller (Mach3)

• Mach3 installation manual and instruction manual of NC milling

machine

These are keeping in 3D Micro-manufacturing Laboratory.

All of them are managed by Jun Hee Choi who is M.S in 3DML. If

someone want to use NC machine, then come to our lab and ask to Jun Hee
