Computing device and method for compensating step values of machining device

A non-transitory computer-readable storage medium storing a set of instructions, when executed by at least one processor of a computing device, cause the at least one processor to perform a method for compensating step values for a processing product placed on a machining device, the method comprising:

• controlling a machining tool of the machining device to move to each of benchmark points in a machining program of the processing product in sequence, wherein the machining program is stored in a storage system of the computing device;
• acquiring actual coordinate values of each of the benchmark points by controlling a laser detection device of the machining device to emit a laser beam when the machining tool is moved to each of the benchmark points;
• fitting the actual coordinate values to be a benchmark plane;
• calculating new coordinate values of each of machining points in the machining program by rotating each of the machining points to the benchmark plane according to an angle difference between the benchmark plane and a preset normal plane of the machining device;
• controlling the machining tool to move to each of the machining points in sequence according to the calculated new coordinate values, and acquiring an actual z coordinate value of each of the machining points using the laser detection device;
• calculating a step compensation value in a Z-axis of the each of the machining point according to the actual z coordinate value of each of the machining points;
• and
• transmitting a calculated step compensation value in the Z-axis of the each of the machining points to the machining device.
