Abstract

The invention discloses a method for predicting multi-axis titanium alloy milling force of ball-end milling cutters. The method includes building multi-axis milling force models with consideration oninfluence of inclined angles of cutters on cut-in angles and cut-out angles on the basis of mechanics models of the three-axis ball-end milling cutters; carrying out cutting experiments; identifying milling force coefficients by means of linear regression according to measured cutting force at different feed speeds; carrying out simulation analysis on influence of machining parameters and geometric parameters of the cutters on the cutting force. The method has the advantage that certain theoretical bases can be provided for optimizing multi-axis milling machining technological methods.

Description

technical field [0001] The invention relates to the field of metal material machining, in particular to a method for predicting the milling force of multi-axis milling of a titanium alloy with a ball-end milling cutter. Background technique [0002] Milling is one of the main methods for surface forming of parts. With the continuous development of numerical control technology, it is widely used in the machining of complex surfaces. Ball nose milling cutters are widely used in multi-axis finishing surfaces due to their better adaptability, and the orientation of the tool has a significant impact on the milling process and workpiece surface quality. Parts with good surface integrity play an important role in their fatigue performance, corrosion resistance, stability and reliability. The excellent properties of titanium alloys make it widely used in aviation, aerospace and other fields. However, compared with other materials, titanium alloys have poor machinability, which affe...
