If it is only operated, there is no difficulty, and it is no different from the three-axis. The program adds an A-axis rotation axis. The simple point of four-axis processing is to rotate the angle of the workpiece, and then process it, which can save the number of clamping times. The complex is XYZ4, four-axis linkage, which can process more complex workpieces, such as impellers, which need to be programmed with software, which is difficult.
How to set the processing origin of the four-axis machining center, directly select back to the origin, and then press and hold a+ until the value of a on the screen becomes zero.
When the four axes are at 0 degrees, find the center of the x and y axes (a round bar is clamped on the four axes), then rotate the four axes by 90 degrees, use a watch or a standard bar to make the main axis coincide with the end face, then the original setting The distance from the origin to the end face of the round bar at 90 degrees on the four axes is the radius of rotation.
Generally, there are many unilateral benchmarks in the X direction, and there are also points in the unilateral Y direction. In the Z direction, you only need to clamp a round bar on the 4th axis and use a dial indicator to measure the height of the worktable and the center of the round bar. The obtained height difference is first corrected into the coordinate system, so that the tool setting can be performed directly on the worktable.
