When Type 2 is specified, the X-Axis PQ path is allowed to vary (for example, the X-Axis tool path can reverse direction).

The X-Axis PQ path must not exceed the original starting location. The only exception is the ending Q block.

Type 2 roughing, when Setting 33 is set to YASNAC, must include R1 (with no decimal) on the G71 command block.

Type 2, when Setting 33 is set to FANUC, must have a reference move, in both the X and Z Axis, in the block specified by P.

Roughing is similar to Type 1 except after each pass along the Z Axis, the tool follows the path defined by PQ. The tool then retracts parallel to the X Axis by a distance defined in Setting 73 (Canned Cycle Retraction). The Type 2 roughing method does not leave steps in the part prior to finish cutting and typically results in a better finish.
