Optimization of free-form surface machining using parallel planes strategy and torus milling cutter

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

Computing Cutter Engagement Values in Milling Tessellated Free-Form Surfaces

High speed milling (HSM) has great potential use in die/mold cutting, but traditional machining plans do exploit HSM capabilities effectively. An important consideration for in HSM is to limit cutting force variations, and one way to do so is to reduce Cutter-Workpiece engagement (CWE) variations. CWE is measured as the area of the tool instantaneously engaged with the part. Estimating CWE as a...

Correlation between machining direction, cutter geometry and step-over distance in 3-axis milling: Application to milling by zones

Computer-Aided Manufacturing (CAM) occupies an increasingly important role in engineering with all it has to offer in terms of new possibilities and improving designer/manufacturer productivity. The present study addresses machining of free-form surfaces on a 3-axis NCmachine tool. There have recently been a large number of studies devoted to planning tool paths on free-form surfaceswith variou...

Optimization of Machining Parameters for Face Milling Operation using ANOVA

To remain successful in today’s competitive market, the manufacturers should rely on their Engineers and production professionals for quick and effective manufacturing setup and also to achieve Quality products. The machining process on a CNC Milling is programmed by speed, feed rate, and cutting depth, which are frequently determined based on the job shop experiences However, the machine perfo...

Machining Free-Form Surfaces

This paper presents an analytical method for planning an efficient tool-path in machining free-form surfaces on 3-axis milling machines. This new approach uses a nonconstant offset of the previous tool-path, which guarantees the cutter moving in an unmachined area of the part surface and without redundant machining. The method comprises three steps: (1) the calculation of the tool-path interval...
