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...

A Geometric Algorithm for Finding the Largest Milling Cutter

In this paper, we describe a new geometric algorithm to determine the largest feasible cutter size for 2-D milling operations to be performed using a single cutter. In particular: 1. We give a general definition of the problem as the task of covering a target region without interfering with an obstruction region. This definition encompasses the task of milling a general 2-D profile that include...

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...

Finding the Maximal Cutter for 2-d Milling Operations

NC machining is being used to create increasingly complex shapes. These complex shapes are used in a variety of defense, aerospace, and automotive applications to (1) provide performance improvements, and (2) create high performance tooling (e.g., molds for injection molding). The importance of the machining process is increasing due to latest advances in high speed machining that allows machin...
