All tools in the machine share the same spindle and program zero; this implies which offset-related concept?

All tools in the machine share the same spindle and program zero; this implies which offset-related concept?

• A. Workshift offset is identical for every tool
• B. The tool length offset must be zero
• C. The DXF file must be loaded
• D. The CAM must be disabled

Answer: (A)

The key idea is how the machine references the part: the work offset defines the origin of the part in machine coordinates, and this origin is the same for every tool. If all tools share the same spindle and use the same program zero, they are all operating from the same work coordinate system. That means the work offset value—the position of the part origin—is identical for every tool. Tool length offsets can differ to account for each tool’s length, but they don’t change where the origin is defined in the work coordinate system. The other options don’t follow from having the same spindle and program zero. The tool length offset doesn’t have to be zero for all tools, it just needs to compensate tool lengths. Loading a DXF file or disabling CAM isn’t dictated by this shared origin situation.
