Work Offsets (Multi-Vises)

- Each vise will have a different work offset number.
- Work offsets are in the upper left corner of each part.
  - You will need to establish each work offset for each vise.
  - Parts that are on the left side of the spindle when the machine is at home position will be a negative  "X' value.
  - Parts on the right side of the spindle at machine home will be a positive "X" value.
  - In most cases the "Y" values will always be a negative value.
