3D Parametric Modelling of Milling Cutter Geometry from Analytical Analysis

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...

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

A parametric approach to 3D dynamic geometry

Dynamic geometry systems are computer applications allowing the exact on– screen drawing of geometric diagrams and their interactive manipulation by mouse dragging. Whereas there exists an extensive list of 2D dynamic geometry environments, the number of 3D systems is reduced. Most of them, both in 2D and 3D, share a common approach for the management of geometric constructions, using numerical...

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...

Sketch-based Interface for 3d Parametric Modelling

In this paper we present an experimental prototype called GEGROSS (GEsture & Geometric ReconstructiOn based Sketch System). This application allows using freehand sketches to create 3D parametric models onto a Tablet-PC. The modelling process consists of two stages. First, the user introduces the geometry of the 2D section using continuous sketches composed by line segments, circles and arcs, a...
