The offset for tool length is described as being oriented relative to the programmed path in which way?

• A. Perpendicular to the programmed path
• B. Parallel to the programmed path
• C. Along the X axis
• D. Along the Y axis

Answer: (A)

Tool length offset is about adjusting how high or low the tool sits relative to the workpiece as it follows a path. This compensation acts along the tool’s axis, which is vertical to the work plane, so it is described as being perpendicular to the programmed path. The path defines movement in the XY directions, while the offset changes the Z position to maintain proper clearance and depth. If the offset were described as parallel to the path or along X or Y, it would move the tool along the travel direction or sideways instead of correcting its vertical distance, which would not properly account for differing tool lengths.
