The reason why the axis does not move in the manual mode of the wheel CNC lathe
When the wheel CNC lathe is operated manually, the machine coordinate axis does not move and the coordinate value does not change. The M, S, T functions are performed normally and the system has no alarm display.
Analysis and solution: In this example, the system did not generate an alarm when the fault occurred, and the functions of M, S, and T were normal. Based on this, it can be initially determined that the CNC system, servo drive, etc. should have no fault. Therefore, the manual conditions can be analyzed, carefully check the manual direction key input, manual direction selection, etc. are normal, and then carefully observe the operation panel "now position" page and found that the manual rate, the actual rate, the feed rate is zero . The reason for confirming that the axis is not manually generated is that the manual movement speed is zero, and the percentage of the feedrate is re-adjusted, and manual operation returns to normal.
To position the No. 1 knife point to a known point on the workpiece, after the relevant command is correctly entered in the program input mode (MDI), the M and S commands are executed normally, the machine coordinate axis is moved, and the CRT screen shows the correct position. However, the tool tip did not run to a predetermined position and the system did not display an alarm.
Analyze and solve: Because the process of the machine tool back to the fixed point is normal, it does not reach the set position. Such failures are usually related to tool compensation. Examine the tool tool compensation execution status and find that the tool function is T0103, and No. 1 tool executes the tool compensation value of No. 3 tool, which causes the tool tip to be unable to run to the predetermined position. Enter T0101 again under MDI to resolve the problem.
