在塑料模具制造中经常遇到的凹腔铣削中，要求尽可能缩小精铣时获得的表面粗糙度值与进一步精加工操作将满足的表面粗糙度值之间的间隔。切削路径策略的实施和选择以及合适的切削参数对表面粗糙度有着重要的影响。每个变量对表面粗糙度的影响都是已知的，但是，在它们的组合中揭示了什么样的结果却无法清楚地估计。本研究的目的是，首先，调查使用高速钢端米尔斯的DIN 1.2738模具钢的最佳切削特性。考虑的切削参数是切削速度、进给速度、切削深度和步距。第二个目的是确定的刀具路径策略的影响时，采用在口袋铣削。这两个目标将通过使用田口参数设计来解决。(c)2007 Elsevier B.V.保留所有权利。
In pocket milling which is often encountered in plastic mould manufacture, the demand is to narrow the interval between the surface roughness values obtained at finish milling and the surface roughness values will be met by further finishing operations as far as possible. The implementation and selection of cutting path strategies with appropriate cutting parameters have significant effect on surface roughness. The effect of every single variable on surface roughness is known, however, what kind of results is revealed in their combinations cannot be clearly estimated. The aim of this study is, first, to investigate optimum cutting characteristics of DIN 1.2738 mould steel using high-speed steel end mills. The cutting parameters considered are cutting velocity, feed rate, depth of cut and step over. The second aim is to identify the effects of cutter path strategies when employing in pocket milling. The both aims will be addressed by means of using Taguchi parameter design. (c) 2007 Elsevier B.V. All rights reserved.
