Programming technology functions (cycles)
10.5 Contour milling
For machining in the opposite direction, contours must not consist of more than 170 contour
elements (incl. chamfers/radii). Special aspects (except for feed values) of free G code input
are ignored during path milling in the opposite direction to the contour.
Note
Activating G40
Before calling the cycle, we recommend that G40 is activated.
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.

Programming of arbitrary contours
The machining of arbitrary open or closed contours is generally programmed as follows:
1. Enter contour
You build up the contour gradually from a series of different contour elements.
Define the contour in a subprogram or in the machining program, e.g. after the end of
program (M02 or M30).
2. Contour call (CYCLE62)
You select the contour to be machined.
3. Path milling (roughing)
The contour is machined taking into account various approach and retract strategies.
4. Path milling (finishing)
If you programmed a finishing allowance for roughing, the contour is machined again.
5. Path milling (chamfering)
If you have planned edge breaking, chamfer the workpiece with a special tool.
Path milling on right or left of the contour
A programmed contour can be machined with the cutter radius compensation to the right or left.
You can also select various modes and strategies of approach and retraction from the contour.
