A rotating tool is a cutting edge that cuts wood during rotation. Therefore, errors such as errors in tool machining, assembly, sharpening, and tooling, as well as errors in the shaft vibration are ultimately reflected by the cutting edge rotating in the axis of the tool axis and completing the cutting process. In other words. The positional accuracy of each cutting edge to the axis of the tool axis is the ultimate direct factor determining whether the width and width of the milling ripple are uniform. Therefore, we define the position error of the cutting edge on the axis of the machine tool axis as the position accuracy of the cutting edge. It can indicate the accuracy of the radial circle runout tolerance value of the cutting edge to the axis of the tool axis.
The accuracy of loading is the error caused by the installation of the blade on the cutter body or the installation of the cutter head on the cutter shaft. The accuracy of the position of the cutter and the cutting edge is not a water, and the two cannot be confused. The accuracy of the tooling is included in the accuracy of the cutting edge position. In addition, the measurement standards of the two are different. The accuracy of the tooling is usually based on the cylindrical surface of the planer body or the mandrel. The accuracy of the cutting edge position is based on the axis of the machine tool. Benchmark.
According to the previous analysis, although the effective cutting edge participates in the formation of the milling surface, since the diameters of the cutting circles of all the cutting blades are not completely equal, the width and width of the milling surface are not uniform. Although the ideal cutting circle cannot be achieved, we can make the difference between the effective cutting circle and the ideal shred diameter as small as possible. We call this cutting circle with the smallest possible diameter difference as the best cutting circle. The best cutting circle is obtained when we approach the diameter of the effective cutting circle between the critical cutting circle and the ideal cutting circle to the ideal cutting circle. The higher the cutting edge position accuracy, the better the milling surface roughness. The opposite is true. Invalid cutting circle when the cutting edge position accuracy value is equal to the effective cutting edge determination value.
