Development Of Cutter Geometrical Feature For Machining Thin Wall Part

Demand for cost-effective aircrafts fabrication has motivated the aerospace industry to use nontraditional materials and new aircraft structural design. New aircrafts are designed with monolithic component to replace large number of assembled component. For manufacturers, high-performance cutting t...

Development Of Cutter Geometrical Feature For Machining Thin Wall Part
description Demand for cost-effective aircrafts fabrication has motivated the aerospace industry to use nontraditional materials and new aircraft structural design. New aircrafts are designed with monolithic component to replace large number of assembled component. For manufacturers, high-performance cutting tool is essential as more than 80% of the material is removed to produce the monolithic component. Most of the monolithic components have thin-wall feature with low stiffness and deformation is more likely to occur in its machining process, resulting in dimensional surface errors. Most of the existing research on machining thin-wall component merely focused on the process planning and there was no scientific study on the effects of cutter geometric feature on component failure. Tool geometry has a direct influence on the cutting performance and should be taken into consideration. In this research, due to the importance of machining efficiency, development of new cutter design specifically for machining thin-wall components are studied. This study consists of both experimental and statistic techniques to evaluate the machining performance associated with the cutter geometry for different types of end mill, namely variable helix constant pitch (VHCP), variable helix variable pitch (VHVP) and tabular helix constant pitch (THCP).
