Time-Efficient Trochoidal Tool Path Generation for Milling Arbitrary Curved Slots

Journal of manufacturing science and engineering, 2019
Trochoidal (TR) tool paths have been a popular means in high-speed machining for slot cutting, owing to its unique way of cyclically advancing the tool to avoid the situation of a full tool engagement angle suffered by the conventional type of slot ...

An adaptive tool path generation algorithm for precision surface machining

Computer-Aided Design, 1998
Abstract In this paper an adaptive CNC tool path generation algorithm for precision machining of parts with free-form surfaces is proposed. It is aimed at developing a generic CNC tool path generation methodology suitable for machining parts having analytical curves/surfaces and/or sculptured (parametric) surfaces, as opposed to most ...

Tool-path generation for clean-up machining

1998
The purpose of clean-up machining is to remove uncut volumes, which are left at concave regions after finish-machining, by employing small-size cutters. The clean-up UMOs to be discussed in this chapter are the fillet-cut [BEM] and pencil-cut [BEM], where BEM denotes ball-endmill cutter.

Optimization method of tool path generation considering the edge of lenslets for a microlens array in FTS diamond turning.

Applied Optics, 2019
Shape accuracy is an important parameter for evaluating the quality of microlens arrays. In fast tool servo (FTS) diamond turning, the generation of tool path has a significant influence on shape accuracy.

Efficient Tool Path Generation for √3 Subdivision Surface

2006 International Conference on Mechatronics and Automation, 2006
An approach of three-axis NC cutter path generation for √3 subdivision surface is proposed. A computing formula for error estimating √3 subdivision surface is derived. Using the formula, one can predict how many steps of subdivision are necessary to meet a user-specified tolerance without subdivision the meshes actually. Tool path planning is generated

Adaptive tool path generation from measured data

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2004
Conventional algorithms for tool path generation from measured points did not use the region-by-region idea to generate adaptive tool paths since it is difficult to obtain geometric information of scattered points directly, which is necessary for adaptive tool path generation. This paper presents a new strategy for determining geometric information of

Incomplete 2-manifold Mesh Based Tool Path Generation

Transactions of the Korean Society of Mechanical Engineers A, 2005
This paper presents a new paradigm for three-axis tool path generation based on an incomplete two-manifold mesh model; namely, an inexact polyhedron. When geometric data is transferred from one system to another system and tessellated for tool path generation, the model does not have any topological data between meshes and facets.

Fundamentals of tool-path generation and validation

1998
The purpose of this chapter is to provide an overview of tool-path generation and validation for sculptured surface machining (SSM). Major topics to be discussed in this chapter include: (1) issues in planning tool-path topology and selecting milling-strategy options, (2) tool-path resolution planning, (3) CL-data computation, (4) cutter-interference ...

Constant engagement tool path generation for convex geometries

Journal of Manufacturing Systems, 2000
Contour-parallel and direction-parallel machining strategies have gained nearly universal acceptance for simple 212D material removal tasks. When the mechanics of the milling process are considered, widely varying cutter engagements and sharp velocity discontinuities are found to significantly limit the efficiency of these approaches.
