1. There is a phenomenon of increasing or decreasing in each process of the workpiece
Causes: programming error; Unreasonable system parameter settings; Improper configuration settings; Regular and periodic changes in mechanical transmission components
Solutions: Check whether the instructions used in the program are executed according to the required trajectory specified in the manual. You can use a dial indicator to determine whether the dial indicator is positioned at the starting point of the program and whether the drag board returns to the starting position after the program ends. Repeat the execution even if you observe the results and grasp the pattern; Check if the system parameters are set reasonably or deemed to have been modified; Whether the relevant machine tool configuration meets the requirements for single calculation of coupling parameters in connection calculation, and whether the pulse equivalent is accurate; Check whether the transmission part of the machine tool is damaged, whether the gear coupling is even, and whether there are periodic and regular faults. If there are any, check the key parts and eliminate them.
2.Unstable size changes caused by the system
Causes: Unreasonable system parameter settings; Unstable working voltage; The system is affected by external interference, resulting in system out of step; Capacitance has been added, but the impedance between the system and the driver does not match, resulting in the loss of useful signals; Abnormal signal transmission between the system and the driver; System damage or internal failure.
Solutions: Whether the speed and acceleration time are too large, whether the spindle speed and cutting speed are reasonable, and whether the operator's parameter modifications have caused changes in system performance; Install voltage stabilizing equipment; Ground the ground wire and ensure it is reliably connected, and add anti-interference absorption capacitance at the pulse output contact of the driver; Select the appropriate capacitor model; Check whether the signal connection line between the system and the driver is shielded, whether the connection is reliable, and whether the system pulse occurrence signal is lost or increased; Send the motherboard to the factory for repair or replacement.
