Dimensional control skills for stainless steel parts processing
Modify tool offset value to ensure dimensional accuracy
According to stainless steel parts machining manufacturers, when the workpiece error exceeds the workpiece tolerance due to the first tool setting error or other reasons, and the processing requirements cannot be met, the workpiece can be modified to achieve the required size by modifying the tool compensation. The method to ensure the radial size is as follows:
Absolute coordinate input method
According to the principle of "large reduction, small increase", modify the tool compensation at 001～004. If the workpiece size is larger by 0.1mm when cutting the groove with the No. 2 cutting tool, and the tool compensation display at 002 is X3.8, you can enter X3.7 to reduce the No. 2 tool compensation.
Relative coordinate method
As in the above example, input U-0.1 at 002 cutter compensation, and the same effect can also be obtained.
The same is true for the cnc operating of the axial size. For example, if you use the No. 1 external tool to machine a certain shaft segment, and the size is longer than 0.1mm, you can enter W0.1 at the 001 tool offset.
Semi-finish machining eliminates the influence of screw gap to ensure dimensional accuracy
According to the analysis of stainless steel parts processing manufacturers, for most cnc machining, after a long period of use, due to the influence of the screw gap, the size of the processed workpiece often appears unstable. At this time, we can perform a semi-finishing process after roughing to eliminate the influence of screw clearance. For example, after rough machining the outer circle with No. 1 tool G71, you can input U0.3 at 001 tool compensation and call G70 fine turning once. After stopping the measurement, input U-0.3 at 001 tool compensation and call G70 fine turning again. . After this semi-finished turning, the influence of the screw gap is eliminated, and the stability of the dimensional accuracy is ensured.
