Optimization and correction of the tool path of the five-axis milling machine: Part 2: Rotations and setup
نویسنده
چکیده
We present two new algorithms (which supplement Algorithms 1, 2 and 3 presented in part 1) to optimize the tool path of the five-axis numerically controlled milling machine. Algorithm 4 optimizes a set of feasible rotations. Algorithm 5 presents a least-square optimization with regard to a setup of the machine © 2006 IMACS. Published by Elsevier B.V. All rights reserved.

Five-Axis Tool Path Optimization Using Rotations and Orientation
This paper presents the algorithms to interactively optimize the tool path of the five-axis milling machine. The algorithms employ the inverse kinematics to derive the corresponding trajectories (rotation and translation movement) of the five-axis machine. The trajectory of the tool path is not unique and depends on the initial set up of the workpiece as well as the combined rotations of the ma...
متن کاملOptimization and correction of the tool path of the five-axis milling machine: Part 1. Spatial optimization
We introduce three algorithms for optimization of a tool path of a numerically controlled five-axis milling machine. The unifying idea is a flexible geometric structure which adapts itself to a certain cost function defined on the required part surface. Algorithm 1 is based on the variational grid generation, Algorithm 2 is based on a new modification of the space filling curves techniques. Alg...

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 کاملImproved Tool Positioning in 5-Axis Flank Milling by Simultaneous Perturbation Stochastic Approximation
This paper presents an improved tool positioning strategy in the 5-axis flank milling of a ruled surface by using simultaneous perturbation stochastic approximation (SPSA) techniques. The SPSA allows the near-global optimization of the machining error, even though the corresponding objective is not formulated as a closed-form representation. It adjusts all cutter locations of a tool path simult...
