Sequence of Program Steps<br />

Milling an outside contour<br />

Programming step Key/Function Refer to Section<br />

1 Create or select program 4.4<br />

Input: Program number<br />

Unit of measure for programming<br />

2 Define workpiece blank for graphic display G30/G31 4.4<br />

3 Define tool(s) G99 4.2<br />

Input: Tool number T...<br />

Tool length L...<br />

Tool radius R...<br />

4 Call tool data T... 4.2<br />

Input: Tool number<br />

Spindle axis G17<br />

Spindle speed S...<br />

5 Tool change<br />

Input: Feed rate (rapid traverse) G00 e.g. 5.4<br />

Radius compensation G40<br />

Coordinates of the tool change position X... Y... Z...<br />

Miscellaneous function (tool change) M06<br />

6 Move to starting position 5.2/5.4<br />

Input: Feed rate (rapid traverse) G00<br />

Coordinates of the starting position X... Y...<br />

Radius compensation G40<br />

Miscellaneous function (spindle on, clockwise) M03<br />

7 Move tool to (first) working depth 5.4<br />

Input: Feed rate (rapid traverse) G00<br />

Coordinate of the (first) working depth Z...<br />

8 Move to first contour point 5.2/5.4<br />

Input: Linear interpolation G01<br />

Radius compensation for machining G41/G42<br />

Coordinates of the first contour point X... Y...<br />

Machining feed rate F...<br />

if desired, with smooth approach: program G26 after this block<br />

9 Machining to last contour point 5 to 8<br />

Input: Enter all necessary values for<br />

each contour element<br />

if desired, with smooth departure: program G27 after the last<br />

radius-compensated block<br />

10 Move to end position 5.2/5.4<br />

Input: Feed rate (rapid traverse) G00<br />

Cancel radius compensation G40<br />

Coordinates of the end position X... Y...<br />

Miscellaneous function (spindle stop) M05<br />

11 Retract tool in spindle axis 5.2/5.4<br />

Input: Feed rate (rapid traverse) G00<br />

Coordinate above the workpiece Z...<br />

Miscellaneous function (end of program) M02<br />

12 End of program<br />
