METHOD OF MACHINING ROUND MATERIAL OR THE LIKE BY THE WHIRLING PROCESS

摘要

A method for machining round material and in particular tubes by the whirling process, in which the whirling tool is designed as an annular cutting tool having an internal tooth system. The center point of the whirling tool is guided from the start on a path or curve so that a tube wall, for example, is not cut through by a linear feed but by a curve-like feed. This curve is followed via a CNC system. Due to the whirling process, which starts immediately, the length of cut of the tool in the workpiece is given a virtually uniform value just after the start of machining so that the chip volume can be optimized. In this way, the radial and tangential forces on the tool can also be reduced, which leads to optimization of the tool.
