ABSTRACT

Contemporary advances in manufacturing are moving towards the diversification of interpolation methods in Computer Aided Manufacturing (CAM) softwares thanks to the growing need of free-forms of high quality. New interpolations such as ‘Bspline’ and ‘Cspline’ provide accurate toolpaths, but they generate significant machining errors. The nodes insertion technique is one of compensation methods of those errors. This paper presents a study of the influence of this compensation method on the manufacturing process: dynamic behavior of machine-tools, errors of controller, and surface quality. To make this study, Bspline and Cspline interpolations, errors generated, and the compensation method are defined. In addition to that, feed rate, cycle time and roughness before and after compensation are measured in order to exanimate the impact of the nodes insertion method. The present work aims to deliver a framework that demonstrates how manufacturing companies with such specific parameters optimization can improve smartness and machining efficiency.

抽象的

由于对自由形式的高质量的需求不断增长，当代制造业的发展正在朝着计算机辅助制造（CAM）软件中插值方法的多样化发展。诸如“ Bspline”和“ Cspline”之类的新插补可提供精确的刀具路径，但会产生明显的加工误差。节点插入技术是这些误差的补偿方法之一。本文介绍了这种补偿方法对制造过程的影响的研究：机床的动态行为，控制器的误差以及表面质量。为了进行这项研究，定义了Bspline和Cspline插值，产生的误差以及补偿方法。除此之外，进给速度 测量补偿前后的循环时间和粗糙度，以验证节点插入方法的影响。本工作旨在提供一个框架，该框架演示具有此类特定参数优化的制造公司如何提高智能性和加工效率。
