Modeling and Analysis for Five-Axis High Speed Milling Process Based on Cutter Optimal Kinematics Performance

The overall goal of the research is the integration of geometric and mechanistic models for cutting process simulation and feedrate optimization. Five-axis milling methods are used in industries such as aerospace, automotive and mold for free-form surface machining. In these process, surface quality and material removal rate are of very important. Conservative cutting parameters have been mostl...

Study of the effective cutter radius for end milling of free-form surfaces using a torus milling cutter

Experimental Study on Milling CFRP with Staggered PCD Cutter

Carbon fiber reinforced plastics (CFRP) have good physical properties, such as high specific strength and high specific modulus. However, cutting delamination, tearing and burr, etc. often occur in the machining process of CFRP, which results in the uncontrollability of machining surface quality and serious tool wear. In this paper, milling of CFRP with a staggered cutter was carried out, the c...

Sliding Friction Contact Stiffness Model of Involute Arc Cylindrical Gear Based on Fractal Theory

Gear’s normal contact stiffness played an important role in the mechanical equipment. In this paper, the M-B fractal model is modified and the contact surface coefficient is put forward to set up the fractal model, considering the influence of friction, which could be used to calculate accurately the involute arc cylindrical gears’ normal contact stiffness based on the fractal theory and Hertz ...

Cutter Path Generation For 2.5D Milling By Combining Multiple Different Cutter Path Patterns

Different cutter path patterns have been shown to be efficient for different types of pocket geometries. However, for certain types of complex pockets, no single type of pattern produces efficient cutter paths throughout the pocket. In this paper, different cutter path patterns are systematically analysed and several existing heuristics for selecting cutter path patterns are discussed. Based on...
