SETTING OFFSETS
To machine a part accurately, the mill needs to know where the part is located on the table
and the distance from the tip of the tools to the top of the part (tool offset from home
position).
To manually enter offsets:
1. Choose one of the offsets pages.
2. Move the cursor to the desired column.
3. Type the offset valu
