Current situation: Each workpiece must be paused, manually trial cut, input data, and continue processing.

Appeal: Find a simpler operation process.

Cause: The position of the inner hole chamfering tool relative to the workpiece cannot be determined.

Analysis:

1) After the outer circle is processed, the X-axis coordinate of the starting point of the chamfering tool can be determined.

2) The inner hole is not processed, and the X-axis coordinate of the end point of the chamfering tool cannot be determined.

3) The end face is not processed, and the Z-axis coordinate of the starting point of the chamfering tool cannot be determined.

Since it is CNC lathe processing, the more reasonable processing technology should be:

1) The hole chamfering should be arranged after the end face and inner hole finishing or semi-finishing.

2) At least the end face should be turned once to determine the Z-axis reference point of the workpiece.

3) After the outer circle and end face are processed, the position of the chamfering tool on the Z axis has been determined, and the starting point in the X direction is at the maximum diameter of the hole.

4) If the inner hole has been processed, the coordinates of the processing end point can be calculated.

5) If the inner hole has not been processed yet, the X-axis end point coordinate value can only be determined according to the minimum hole diameter of the blank.

2) If the hole is relatively small, for example, the hole diameter is less than 20 mm, you can directly use a solid carbide chamfering tool and feed in the axial (Z) direction.

3) If it is a medium-diameter hole, for example, the hole diameter is less than 63 mm, you can choose a welded chamfering cutter and process it in the axial (Z) direction.

4) If the hole diameter is relatively large, the chamfering length is relatively long, or this process is not the final processing, the process needs to be reasonably arranged.

There are no workpiece drawings, and there are no before and after process instructions. I just propose a few solutions based on the situation you mentioned.
