Programming technology functions (cycles)
9.3 Contour turning
For single-channel systems, cycles do not extend the name for the programs to be
generated.
Note
G code programs
For G code programs, the programs to be generated, which do not include any path data,
are saved in the directory in which the main program is located. In this case, it must be
ensured that programs, which already exist in the directory and which have the same name
as the programs to be generated, are overwritten.
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 freely select the machining type (roughing, finishing or complete machining -
roughing + finishing). During contour roughing, parallel cuts of maximum programmed infeed
depth are created. Roughing is performed to the programmed allowance.
You can also specify a compensation allowance U1 for finishing operations, which allows
you to either finish several times (positive allowance) or to shrink the contour (negative
allowance). Finishing is performed in the same direction as roughing.
