Hydrostatic analysis for modelling and simulation of high‑precision CNC tool grinding machine

Five-axis CNC tool grinder is mainly used for machining milling cutters and other tools, in the process of machine tool machining, the static deformation of the machine structure, vibration and thermal deformation problems will make the precision of the machine tool will be reduced, and this will affect the quality of the product. This paper takes the DKP 10A 5-axis CNC grinder as the research object, and carries out static simulation analysis on the whole machine tool and important parts by using finite element simulation and relevant experiments. The overall machine tool is subjected to gravity load only, and at the same time subjected to gravity load and grinding force load in two cases of static analysis, to get the deformation of the machine tool in the static mechanics, to assess the machine tool due to the change of static load and the error that will be generated. At the same time, a finite element modal analysis was carried out on the machine tool as a whole to determine its modal vibration pattern and modal frequency. It provides a reference for the optimisation of the static performance of the machine tool structure.
