Lathe part-off operation

The lathe part-off operation is final operation in the revolutions part machining. It is designed to disjoint the ready machined part from the workpiece and shape the back side of a part.

The Job assignment tab for the operation allows to add Parting off cycle and also some additional machining cycles to be possible to prepare the workpiece before cutting off, for example make groove with the same tool.

The Part-off cycle automatically defines cutting profile at the maximal (left or right) coordinate of the part from highest to lowest point of the workpiece. Left or right side depend on machining side property that seen as green arrow next to the start profile point. Click it to change side.

There is the possibility to create the chamfer or rounding on the external diameter of the part and the special strategy for the chip breaking. This mode allows to set the peck length or the peck count. The delay parameter give the possibility to set the pause in the end of the pecks. The pause time can be assigned in seconds or in revolutions.

The following strategies allowed for part-off operation:

• Parting-off cycle;

• Profile;

• Slotting;

• Grooving;

• Zigzag;

See the page of cycle parameters for detailed description of each strategy and Job assignment definition page for geometrical properties.
