Abstract

The invention discloses a fault simulation method of a numerical control machine. In the method, fault simulation of the numerical control machine is realized by establishing a machine tool setup information sheet, a fault setup information sheet, a machine tool logic model and a machine tool servo model, embedding machine tool fault points, operating a machine tool simulation model and triggering faults of the machine tool. The method disclosed by the invention is mainly used for solving test conditions of the failure detection function and capacity of top grade numerical control devices and simulating numerical control machine faults, programmable logic controller faults, servo driver and servo motor faults, and main shaft driver and main shaft motor faults. The fault simulation method of the numerical control machine can be used for detecting capacities of the numerical control device such as response, protection and auto recovery on the faults of the numerical control machine.

Description

technical field [0001] The invention belongs to a numerical control device testing method, in particular to a numerical control machine tool fault simulation method. Background technique [0002] In the testing and training of the CNC device, the CNC device needs to be used together with the machine tool and the control cabinet. This method is not only costly, but also very inconvenient. In order to design a convenient and cheap fault simulation device and solve the fault detection function and ability of high-end CNC devices, it is necessary to have a convenient and feasible fault simulation method for CNC machine tools to simulate faults of CNC machine tools, programmable controller faults, servo drives and servo motors, Spindle driver and spindle motor failure. The faults of CNC machine tools simulated by this method can be used to detect the response, protection and automatic repair of CNC devices to faults of CNC machine tools. [0003] At present, no similar conveni...
