Programming technology functions (cycles)
10.5 Contour milling
the tool moves with rapid traverse. Material is then removed between the blank contour and
spigot contour.
Note
Execution from external media
If you execute programs from an external drive (e.g. local drive or network drive), you require
the "Execution from external storage (EES)" function.

Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.
Input simple
For simple machining operations, you have the option to reduce the wide variety of parameters
to the most important parameters using the "Input" selection field. In this "Input simple" mode,
the hidden parameters are allocated a fixed value that cannot be adjusted.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
Machining type
You can select the machining type (roughing, base finishing, edge finishing, chamfer) for
milling. If you want to rough and then finish, you have to call the machining cycle twice (block
1 = roughing, block 2 = finishing). The programmed parameters are retained when the cycle
is called for the second time.
Approach/retraction
1. The tool approaches the starting point at rapid traverse at the height of the retraction plane
and is fed in to the safety clearance. The cycle calculates the starting point.
2. The tool first infeeds to the machining depth and then approaches the spigot contour from
the side in a quadrant at machining feedrate.
