Order of drives is inverted as follows when the Close tool path check box is not selected. Drives A, B, C, D are machined in the order D, C, B, A.

  • Before Opposite Hand Machining:

  • After Opposite Hand Machining:

Order of drives is inverted as follows when the Close tool path check box is selected. Drives A, B, C, D are machined in the order A, D, C, B, A. Drive A is the first and last machined element.

  • Before Opposite Hand Machining:

  • After Opposite Hand Machining:

Start and End elements, offsets, and conditions are inverted.

Approach and Leave distances are swapped.

Manual direction is inverted (Left / Right). Local stopping condition and Local restarting direction are updated.
