In order to guarantee the machining precision of parts, CNC carving and milling machine has enough static stiffness, therefore it is necessary for numerical control carving and milling machine tool for structural static analysis, find the main factors influencing the stiffness CNC carving and milling machine tool.
On this basis, the corresponding parts CNC carving and milling machine tool can be structure optimization design, in order to improve the overall rigidity and performance of CNC carving and milling machine tool.
In the field of engineering technology commonly used numerical simulation method to achieve in this job, mainly the finite element method.
KT-
450 CNC carving and milling machine tool top speed of 25000 r/min, the appearance of the structure as shown in the figure below.
Because the process is the effect of dynamic load, vibration, the processing quality is not stable, workpiece surface quality is poorer, the production efficiency is low.
Analysis the main reason is caused by the high speed cutting force caused by vibration.
