Method of measuring machined region, numerical control machine and computer-readable storage medium

A computer numerical control system, comprising:

• at least one data processor;
• and
• at least one non-transitory computer-readable medium storing program instructions which, when executed by the at least one data processor, cause the computer numerical control system to:
• obtain a coordinate of at least one measurement point, wherein the coordinate of the at least one measurement point corresponds to a target position on a surface of a machined material;
• determine a machined region based on the coordinate of the at least one measurement point;
• and
• control a target page to display the machined region.
