Design And Implementation Of Measurement Method Of Five Axis Based On AxiSet

Because of the influence of five axis machine tools by the assembly precision and rotating parts, makes the machine tool structure error appeared to lead to the deviation in the cutter location points, to reduce the machining accuracy of machine tools. Rotary axis performance of the machine tool can be automatic measured by Axi Set five axis measurement device rapidly and accurately in three-dimensional space, but did not provide related functions such as error compensation and domestic numerical control system was not integrated with the involved measurement scheme.In this paper, through the analysis of system integration solution based on the Axi Set device, combined with the existing five axis measurement method, according to the machine tools structure, three types of five-axis machine tools kinematics model was established. Analysis the influence of various machine parameters to the cutter location points, 3D probe-ball of Axi Set device was used for measuring standard sphere from different angles for several times, the positions of standard ball were recorded for each measurement, to calculate the machine parameters accurately combined with the relationship of the five axis transformation. According to the principle of measurement to design the five axis measurement method based on the Axi Set and determine the measurement process, the measurement scheme can be integrated into the domestic numerical control system.The measurement method proposed in this paper correctly describe the characteristics of machine tools to ensure the mechanical parameters and the parameters of the numerical control system are consistent, and has good generality for all kinds of machine models. Overall position error of five-axis machine tools can be measured directly by using Axi Set device, thus cutting down the measuring time and improving the measuring speed, which not only can improve the machining precision of the existing machine tools, but also provide a unified measurement basis for multi-axis machine tool in the future.
