Direct-Drive Bi-Rotary Milling Head Variable Load Thermal Characteristics Analysis

Abstract

Bi-rotary Milling Head in the machining process take direct cutting force, its thermal properties change on the accuracy of machine tool have an important influence. In this paper a wide range of load change processing conditions direct drive type double pendulum Angle milling head thermal properties condition to carry on the analysis, based on solidworks platform set up Bi-rotary Milling Head of the CAD model, the model into ANSYS platform. Determine the Bi-rotary Milling Head structure heat source, convection boundary conditions and constraints, the motor power changes the Bi- rotary Milling Head temperature field model and digital simulation, the varying load processing conditions, A, C thermal characteristic analysis, get the A, C axis load - temperature - time distribution, for the Bi-rotary Milling Head and structure design of high-grade CNC machine straight drive processing technology led to the development of theory and the technology base.
