When the CNC machine tool is used for machining, there are three kinds of the processing indexes such as speed, accuracy and surface quality. Due to the Industry 4.0. the products are gradually oriented towards the trend of low volumes and high product variety. After the machine tool has been shipped from the factory, it will be set a set of standard controller parameter. But this set of controller parameter can’t conform all kinds of processing requirement. Therefore, it is extremely importa

One is getting help from contractors while the second is testing piece by piece in order to cutting down the defect rate. The disadvantages of the solutions are the solutions are not very efficient when facing special processes. Furthermore, it is not easy to find out errors and the whole testing needs to be re-done again.
