5-Axis Flank Milling of Sculptured Surfaces
This chapter covers the various free-form surface flank milling strategies available, focusing in particular on those for ruled surfaces as widely used in defining turbomachine parts. All these positionings seek to reduce interference between the cutting tool and the surface to be milled so as to respect the tolerances dictated by the Design Office. The range of strategies presented goes from t...
متن کاملAn Instantaneous Rigid Force Model For 3-Axis Ball-End Milling Of Sculptured Surfaces
An instantaneous rigid force model for prediction of cutting forces in ball-end milling of sculptured surfaces is presented in this paper. A commercially available geometric engine is used to represent the cutting edge, cutter and updated part geometries. The cutter used in this work is an insert type ball-end mill. Intersecting an inclined plane with the cutter ball nose generates the cutting...
متن کاملGeometric Contribution to 3-axis Milling of Sculptured Surfaces
When we are trying to shape a surface X by 3-axis milling, we encounter a list of problems: First we have to decide if locally the milling tool Σ is able to move along the surface such that its envelope during the motion is the given surface. This is a question involving the curvatures of X and Σ. Second, we want to avoid that while milling in one part of X, Σ intersects another, already finish...
متن کاملGeometric Criteria for Gouge{free Three{axis Milling of Sculptured Surfaces
The paper presents a geometric investigation of collision-free 3-axis milling of surfaces. We consider surfaces with a global shape condition: they shall be interpretable as graphs of bivariate functions or shall be star-shaped with respect to a point. If those surfaces satisfy a local millability criterion involving curvature information, it is proved that this implies globally gouge-free mill...
متن کاملModeling of three-dimensional cutting forces in micro-end-milling
A new nominal uncut chip thickness algorithm for micro-scale end-milling is proposed by considering the combination of an exact trochoidal trajectory of the tool tip and tool run-out, and then the actual uncut chip thickness may be obtained from a comparison between the current accumulative uncut chip thickness and the minimum chip thickness. Due to the intermittency of the chip formation, the ...
