Abstract

This paper studies the effect of cutting parameters on surface generation in ultra-precision turning of a contact lens polymer. Contact lens manufacture wants high accuracy and high surface quality. Surface roughness is mostly used to measure the index quality of a turning process. It has been an important response because it has direct influence toward the part performance and the production cost. Hence, choosing optimal cutting parameters will not only improve the quality measure but also the productivity. This research work is therefore aimed at investigating the effect of cutting parameters (cutting speed, feed rate and depth of cut) on surface roughness of RGP ONSI-56 contact lens polymer with a monocrystalline diamond cutting tool. In this work, cutting speed (A) is found to be the most dominant factor having the highest degree of significance followed by the square of the cutting speed (A2) and the feed rate (B). However, interaction between cutting speed and feed rate (AB) has the lowest degree of significance on the surface roughness.

超高精密车削隐形眼镜聚合物时切削参数对表面粗糙度的影响
研究了隐形眼镜聚合物超精密车削加工中切削参数对表面生成的影响。隐形眼镜制造要求高精度和高表面质量。表面粗糙度主要用来衡量车削过程的指标质量。它直接影响到零件的性能和生产成本,已成为一个重要的回应。因此,选择最优的切削参数不仅可以提高质量指标,还可以提高生产率。因此,本研究工作旨在研究切削参数(切削速度、进给速度和切削深度)对RGP ONSI-56隐形眼镜聚合物表面粗糙度的影响。研究发现,切削速度(A)是最主要的影响因素,对表面粗糙度的影响程度最高,其次是切削速度(A2)和进给速度(B)的平方。而切削速度和进给速度(AB)之间的相互作用对表面粗糙度的影响程度最低。

期刊介绍: IJCMSSE is a refereed international journal that aims to provide a blend of theoretical and applied study of computational materials science and surface engineering. The scope of IJCMSSE original scientific papers that describe computer methods of modelling, simulation, and prediction for designing materials and structures at all length scales. The Editors-in-Chief of IJCMSSE encourage the submission of fundamental and interdisciplinary contributions on materials science and engineering, surface engineering and computational methods of modelling, simulation, and prediction. Papers published in IJCMSSE involve the solution of current problems, in which it is necessary to apply computational materials science and surface engineering methods for solving relevant engineering problems.
