Comparison between multi-point and other 5-axis tool positioning strategies
نویسندگان
چکیده
A method of generating sculptured surfaces at multiple points of contact between the tool and the workpiece was developed and proven viable by the current authors in previous work. They denoted this finish machining method, “Multi Point Machining”, or simply MPM. This paper compares MPM with two other 5-axis tool positioning strategies; namely: the inclined tool, and the principal axis method. It is also compared with 3-axis ball nose machining. Comparisons are conducted using computer simulations and experimental cutting tests. Results obtained show that MPM produced scallop heights that are much smaller than those produced by the other tool positioning strategies. 1999 Elsevier Science Ltd. All rights reserved.

Multi-point tool positioning strategy for 5-axis mashining of sculptured surfaces
Multi-point machining (MPM) is a tool positioning technique used for finish machining of sculptured surfaces. In this technique the desired surface is generated at more than one point on the tool. The concept and viability of MPM was developed by the current authors in previous works. However, the method used to generate the multi-point tool positions was slow and labor intensive. The objective...
متن کاملIntersection approach to multi-point machining of sculptured surfaces
Five-axis machining of sculptured surfaces is gaining wider acceptance in many industries. This paper examines the potential of a new tool positioning strategy where the desired surface is machined at more than one point of contact between the desired surface and the cutting tool. The method is called Multi-Point Machining or simply MPM. Intersection theory is used to gain insight into the mult...
متن کاملMeasurement of Volumetric Positioning Accuracy of a 5-axis Machine By Laser Vector Technique
For a 5-axis machine tool, the 3D volumetric tool-tip positioning accuracy is very important for parts accuracy and quality assurance. Just calibrate the 3 linear axes and the 2 rotational axes is not enough. There are straightness errors for each of the 3 linear axes, and squareness errors between the 3 linear axes, misalignment errors between the linear axes and the rotary axes. Hence, it is ...
متن کاملDeriving Fuzzy Inequalities Using Discrete Approximation of Fuzzy Numbers
Most of the researches in the domain of fuzzy number comparisons serve the fuzzy number ordering purpose. For making a comparison between two fuzzy numbers, beyond the determination of their order, it is needed to derive the magnitude of their order. In line with this idea, the concept of inequality is no longer crisp however it becomes fuzzy in the sense of representing partial belonging or de...
متن کاملRolling ball method for 5-axis surface machining
Curvature matching for 5-axis surface machining has been plagued by the complexity of the task. As a result the current tool positioning strategies are likewise computationally complicated. Gouging the surface has been the main concern and has presented the greatest dif®culty in the algorithms. Some of the methods perform exhaustive searches of the surface to avoid gouging while others incremen...
