Description

Technical field [0001] The invention relates to a solvent-free compliance virtual simulation experiment system for testing the functions, performance and accuracy of a numerical control system. Background technique [0002] In recent years, with the continuous development of the national economy, the requirements for manufacturing automation have become higher and higher, solvent-free compound machines have become popular, and the corresponding demand for various CNC systems has also increased, and CNC systems have begun to be mass-produced In the production process of the original numerical control system, the online test method of connecting the servo motor or directly connected to the solvent-free compound machine adopted by the numerical control system becomes infeasible. This test method requires the number of servo motors, the number of compound machines, the cost and Time is very difficult or unbearable for CNC manufacturers. [0003] Numerical control technology refers to ...

Problems solved by technology

The numerical control system itself is also a computer. The test and inspection of its computer characteristics can adopt the mature large-scale computer test method, but the numerical control system is used for the detection of the control ability of various mechanical quantities and switching quantities related to the flow direction of mechanical quantities. General computer detection methods cannot be realized

In the production process of small-scale solvent-free composite machines, it is generally used to connect each CNC system to the servo motor to control its torque and speed, or to install the CNC system on the solvent-free composite machine for actual processing to test the reliability of the CNC system and whether it is Meet the factory standard of the CNC system, but when the CNC system needs to be mass-produced, the above-mentioned detection method becomes unfeasible, and the CNC system manufacturer cannot provide the CNC system with the number of servo motors or solvent-free composite machines and the test time Reach a balance point, and the number of motors that can be controlled by different types of CNC systems is different. One compound machine can only test one CNC system, which is obviously difficult to meet the needs of CNC system manufacturers.
