About Turn Profile
To define cut geometry for a Turning NC sequence, you have to create a Turn Profile. A Turn Profile is a separate feature (similar to a Mill Volume or Mill Window), which you can define either at setup time or when you define an NC sequence. You can then reference the Turn Profile in more than one Turning NC sequence. This functionality enables you to define the cut references once, and then use this definition to create rough, semi-finish, and finish NC sequences.
You can define Turn Profiles in any one of the following ways:
• Click
Turn >
Turn Profile • In the Process Manager, click Insert > Manufacturing Geometry > Turn Profile.
A Turn Profile defines the cut geometry for various types of Turning NC sequences in the following manner:
• The Turn Profile coupled with cut extensions and the workpiece or stock boundary defines the area removed by an Area and Groove turning step. The amount of stock left after the cut is defined by the ROUGH_STOCK_ALLOW, Z_STOCK_ALLOW, and PROFILE_STOCK_ALLOW parameters.
• For Profile turning, you must specify the trajectory of the cut motion for the tool. Then, if the OUTPUT_POINT parameter is set to CENTER (the default), the cut motion will be automatically offset by NOSE_RADIUS in the appropriate direction from the specified trajectory (up for Outside turning, down—for Inside, to the right—for Face). If OUTPUT_POINT is TIP, no offset will be applied.
• For Thread turning, you must specify the first tool movement, which corresponds to the major diameter for an external thread and to the minor diameter for an internal thread.
