摘要 隨著科學技術的發(fā)展，制造業(yè)發(fā)生了翻天覆地的變化，各種先進制造技術正逐漸地應用于制造系統(tǒng)中。制造系統(tǒng)正向著數(shù)字化、集成化、并行化、網(wǎng)絡化及柔性化的方向發(fā)展。在現(xiàn)代制造系統(tǒng)中，數(shù)控加工設備是制造系統(tǒng)的核心設備，是現(xiàn)代制造系統(tǒng)的重要組成部分。數(shù)控加工技術是現(xiàn)代自動化、柔性化及數(shù)字化生產(chǎn)加工技術的基礎與關鍵技術。數(shù)控切削加工工藝參數(shù)及刀具運動軌跡優(yōu)化是發(fā)揮數(shù)控加工設備生產(chǎn)效率的有效途徑。 本文在數(shù)控切削加工工藝優(yōu)化方面主要進行了基于加工特征的刀具軌跡選擇的研究。首先研究確定了銑削加工的加工特征;在此基礎上，建立了基于PowerMILL加工特征的銑刀選擇知識規(guī)則，并將其知識融入PowerMILL加工，實現(xiàn)數(shù)控刀具軌跡的優(yōu)選。 數(shù)控加工刀具運動軌跡是確定數(shù)控加工工藝的重要環(huán)節(jié)。刀具運動軌跡設計質(zhì)量的好壞，將直接影響零件的加工質(zhì)量及加工成本。本文針對典型零件的銑削加工，對幾種刀具運動軌跡進行優(yōu)選。 關鍵詞 數(shù)控加工，刀具選擇，PowerMILL,刀具軌跡
Abstract With the development of science and technology great changes have taken place in the manufacturing. Every kinds of advanced manufacture technology are applying in the manufacture system now. The manufacture system is developing in the direction of numeric ， integration parallelize ， network and flexible. In the system of modern manufacture,NC machining equipment is the core of the manufacture system and the important subassembly of the modern manufacture system. The technology of NC machining is the based and key machining technology of the modern automatic，flexible and numeric. The optimization of NC machining process parameters and the cutting tool path is the available approach of exerting the NC machining equipment productivity. In this paper，we mostly discussed the cutting tool choice based on the feature of cutting process as belongs to the optimization of NC machining process parameters. Firstly we discussed and determined the feature of milling process，based on which we set up the knowledge rules of milling cutting tool choice. We applied the knowledge rules to the expert system of PowerMILL,which realized the cutting tool choice of NC machining. Cutting tool path of NC machining is one of the important parts to determine NC machining process. Whether the tool path quality is good or bad will directly affect the machining and the machining cost of part. The milling cutting tool path creative method of representative part is studied in this paper. We optimized several cutting tool paths.
