官方故障排除步骤
[Cause of error] In Cycle 240 Centering you defined parameter Q343 such that centering is done with respect to the diameter. In a drilling cycle you defined parameter Q395 such that the depth is in reference to the tool diameter. You programmed a cycle for chamfering. The point angle for this must be between 1 and 179 degrees. However, no point angle is defined for the active tool. [Error correction] - Set parameter Q343=0 (centering to entered depth). - Set parameter Q395=0 (depth in reference to the tool tip). - Define the point angle in the column T-ANGLE of the tool table TOOL.T.
