In milling posts, retract moves are included during posting in these situations.
Program Start
- XYZ location in program start is always the first point in the segment.
Tool Change
- XYZ location in tool change is always the first point in the segment.
Segment Start
- If same tool and same feature (typically this happens between rough and finish operations), the XYZ location of the second segment is the same point as the last point in the first segment. This XYZ location is often omitted in posted code because of modality brackets in the post.
- If same tool and different feature but XYZ location is the same (for example roughing and finishing on separate features), the tool retracts to the clearance plane of the second feature as the first move in the second segment.
- If same tool and different feature but XYZ location is different (for example roughing and finishing on separate features with plunge point set), the tool retracts to the rapid plane as the last move in the first segment.
