Axial turning manual helicoidal contouring (with C axis)

Make an axial helicoidal contouring using a rotative tool. Unlike a traditional contouring operation, carried out at a constant altitude, the cycle contains a simultaneous descending move all along the tool path, so that tool wear is reduced.
The positioning of the part and the machining is done with the C axis (Spindle) and NOT with the Y axis even if the machine tool has one.

Activate the default Wcs of the part if it's not the current one.
Select the profile to use.
Check the material side direction
Select the reference face on which the contouring will occur, or input an altitude for the location of the tool path.
Select the tool to use for the operation
Specify the different parameters in the tab dialogue box which appears.
Enter the comment which appears on the machine block listing meant for the NC operator. This comment will also appear when the user wishes to take a look at or modify an operation, using the Operation/ Operations manager function.
Eventually, enter a codified remark which will be interpreted by the post-processor, in a specific manner predefined by the user and the post-processor redactor.
Validate entries made into the dialogue box by clicking on OK.
