What does cutter compensation commands affect in CNC machining?

Cutter compensation commands are specifically designed to adjust the tool path during CNC machining operations. This functionality allows the program to dynamically account for the wear and tear on the cutting tool, or to compensate for differences in tool geometry, without the need to modify the original programmed paths. When these commands are used, they can effectively offset the actual movement of the tool to ensure that it accurately follows the intended contour of the workpiece.

For example, if a tool is slightly larger or smaller than expected, cutter compensation can automatically adjust the path of the tool accordingly, ensuring that the final dimensions of the part remain correct. By affecting the tool paths, cutter compensation commands enhance precision and accuracy in machining operations, crucial for maintaining quality in manufacturing processes.

The other options, while relevant to CNC operations, do not pertain specifically to the functionality of cutter compensation. Speed settings control how fast the machine operates, spindle rotation determines the speed of the cutting tool, and tool offsets involve adjusting parameters for the tool's length and diameter. Each of these elements plays a vital role in the machining process, but they do not directly relate to the path adjustments made by cutter compensation commands.
