After recycling the NC tool blade, the better way is to process and reuse it. The quality of recycling directly affects the precision of the parts processed by the recycling NC tool blade, and also affects the later operation of the NC machine tool. For the recycling errors existing in the recycling NC tool blade, specific improvement measures should be put forward according to the actual situation.
The machining error produced in the process of NC cutter blade machining should be avoided as far as possible under certain circumstances. The programming error is mainly the interpolation error produced by the NC system in NC programming. This is mainly due to the use of straight line or arc segment to avoid the part contour, which affects the machining accuracy of parts. We can increase the number of interpolation nodes, but it will increase the workload of programming.
The error of tool tip arc is that when cutting inner hole, external cause or end face, the tool tip arc will not affect its size and shape, but when machining cone and arc, it is easy to be affected by the tool tip arc and cause over cutting or less cutting. Such error can be eliminated by measuring the radius of the tool tip arc and using the radius compensation function of the tool.
The measurement error of the recovered NC cutter blade is affected by the measuring accuracy of the measuring tool and the operation method of the measurer, which leads to the inaccuracy of the measured size. This error can be compensated. The error of tool setting is mainly produced in the process of tool setting. When the tool moves to the starting point, it is affected by the adjustment proportion value of the operating system. The main solution is to reasonably select the actual adjustment proportion, especially when the tool is close to the starting point, the minimum gear should be used to make the tool accurately positioned at the starting point.
