Geometric algorithms for computing cutter engagement functions in 2.5D milling operations
Geometric algorithms for computing cutter engagement functions in 2.5D milling operations. ABSTRACT Cutter engagement is a measure that describes what portion of the cutter is involved in machining at a given instant of time. During profile milling of complex geometries, cutter engagement varies significantly along the cutter path. Cutter engagement information helps in determining the efficien...
متن کاملComputing 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...
متن کاملA Geometric Algorithm for Finding the Maximal Cutter for 2-d Milling Operations
In this paper, we present a geometric algorithm of finding the maximal cutter for 2-D milling operations. Our algorithm works not only for the common closed pocket problem, but also for the general 2-D milling problems with open edges. We define the general 2-D milling process in terms of a “target region” to be machined and an “obstruction region” that should not intersect with the cutter duri...
متن کاملFinding 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...
متن کاملA 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...
