Method for detecting workpieces by using multi-coordinate mechanical processing machine

The invention provides a method for detecting workpieces by using a multi-coordinate mechanical processing machine. The detected workpieces are directly detected on a worktable of the processing machine after being processed. The method comprises the following steps of: detecting mechanical errors of the multi-coordinate mechanical processing machine; compensating the mechanical errors in a numerical control system of the three-coordinate mechanical processing machine; compensating the mechanical errors in measurement and control software of the multi-coordinate mechanical processing machine; and directly measuring the workpieces on the worktable by using a measuring head; and guiding the work of the machine in the next step, and the like. The method is used for directly detecting the processing workpieces on the multi-coordinate mechanical processing machine, and the detection accuracy of products is improved by compensating the mechanical errors in the numerical control system and the measurement and control software of the multi-coordinate mechanical processing machine.
