精密磨床螺桿組裝量冶具改善個案研究

台灣工具機產業以中小企業為主體，憑藉的是彈性製造及應變的能力，以擅於為客戶訂製產品且物美價廉見長，配合完善的衛星工廠加工體系，具有組裝產能迅速及零件取得容易的優勢。磨床為工具機中最高精密的工作機械，承擔著最後一道製程完工精度的嚴格關鍵要求，是工具機精密科技的實現象徵，為了提升國家高科技產業，日本、德國、美國、義大利、瑞士無不竭盡所能去發展工具機產業。但在人力成本提高、原物料上漲的經濟趨勢及生產成本降低、生產週期縮短…等壓力下，生產線已逐步朝著省時、省力及自動化的方向發展。因此，將TRIZ理論導入冶具設計體系則是工具機發展的一項技術革新，亦是一種能適應現今市場競爭力的設計模式。本研究以精密磨床螺桿組裝為例，將TRIZ理論及研究者相關實務經驗加以整合，從設計方法、冶具改善及個案實證等階段著手，改善出本設備泛用之冶具。最後，並且進一步分析冶具改良後的經濟效益。本研究發現將TRIZ理論導入冶具設計的應用，可提昇冶具設備模組性、實現高品質、低成本、短週期的效果，增加市場競爭力。透過模組化設計應用於組裝製造體系之中，則能提昇現場組裝技術人員及產品多樣化之生產能力，並且有利於組裝生產排程與物流順暢。

In Taiwan, small and medium enterprises take the major parts of machine tool industry. By their flexible production and adaptability, they are known for the inexpensive but exquisite customized products. They cooperate with satellite factories for the thorough processing system, taking the advantage of high assembly capacity and easy access to components. Among all the machine tools, grinding machine possesses the highest precision. It is expected to meet the crucial strict demands for final accuracy in the last step of manufacturing. It can be seen as the symbol of realizing the precision technology in machine tools. To promote the national hi-tech industry, Japan, Germany, America, Italy, and Switzerland all make their efforts to develop machine tool industry. However, based on the economic trends, the labor cost is increasing, the raw material price is raising, the production cost is reducing, and the production cycle is shortened. Under these pressures, production gradually has been developed with the aim to save more time, labor and also be automatic. Thus, it is a technical breakthrough for machinery development to infuse TRIZ theory into jigs designing. This is a new design mode that can adapt to the competitiveness in market. This project takes the assembly of screw on precise grinders as the research model, integrating the theory of TRIZ and researcher’s related personal experiences. It aims to refine the general jigs by the ways of design, jigs improvement, illustration of individual cases. Ultimately, after refining jigs, the further analyses about economic returns can be done. In this research, it is figured out that leading TRIZ into jigs designing possesses great potential, including gaining jigs’ common functions, realizing the high quality, reducing the cost, shortening the cycle, and enhancing competitiveness in markets. If it is used in assembly system, then it can improve assemblers and boost the diversity of products. Also, it is beneficial for production schedule and smooth distribution.
