Problems solved by technology
If it is a machine tool with spindle head swing, this problem is particularly prominent. Once the tool length changes when the tool is replaced, the original program values are all incorrect, and post-processing needs to be performed again, which brings serious problems to actual use. big trouble
and low processing efficiency

The invention discloses a cutter point control method for a rotating tool of a double-rotating-work-table five-shaft machine tool. On the basis of a standard numerical control system with an RTCP (rotating tool center point) function, compiling post treatment is carried out according to the structural form of a five-shaft numerical control machine tool. The post treatment refers to a process for converting cutter position source files into a numerical control program identified by a machine tool control system. An RTCP option function is realized on a control system, the coordinate transformation is calculated through a controller, the processing procedures can maintain unchanged, and for the same batch of parts, the frequent program change due to installing and clamping position change is not needed. Only corresponding coordinate positions need to be written into parameters. Meanwhile, the method also brings following advantages that machined workpieces are diverse, the machining efficiency is improved, and the machining precision is high.
Description
technical field [0001] The invention belongs to the technical field of five-axis machine tool processing, and in particular relates to a tool center tool point positioning error control technology of a five-axis machine tool. Background technique [0002] CNC machine tools are divided into three-axis CNC machine tools, four-axis and multi-axis CNC machine tools (including five-axis and above) according to the number of axes in the coordinate system. Theoretically, for a CNC machine tool with 3 linear axes and 2 rotary axes, the five-axis linkage can realize the continuous processing of complex surfaces, which is generally called a five-axis five-linkage CNC machine tool; if the five-axis positioning is not linked, it can process space Arbitrary orientation points are generally called five-axis positioning CNC machine tools. According to the structural form, five-axis CNC machine tools are divided into double-table swing type, double-spindle milling head swing type, worktabl...
