Rigidity Synthesis and Machining Error Analysis of Machine Tool Chain
With the performance-based CNC machine tool scheme and structural design as the background,the machine tool rigidity chain under the influence of machine tool component motion,load transfer chain and error transmission chain,the machining error under the control of machining process,and the directional rigidity chain on the machine tool layout scheme and The influence law of structural design was studied.The fundamental techniques of component rigidity chain modeling based on superelement and cumulative error prediction model based on the machining process are proposed.Taking a horizontal boring and milling machining center as the object,the space rigidity field of the machine tool workpiece is calculated,and the machining error of the standard contour machining test piece of the boring and milling machine is further predicted.Finally,comparing the model with the results of ANSYS analysis,the method significantly improves the computational efficiency based on ensuring the prediction accuracy.It provides a new idea for the optimization of the design and structure of the machine tool and the optimization of any part machining process.
