机械加工实训是机械类专业教学过程的重要环节。机械加工实训教学内容包括:机械加工入门指导、车削加工、铣削加工、刨削加工、磨削加工。其中车削加工最为重要,实习时间占整个实习的三分之二。而在车削过程中刀具的磨损报废问题十分严重。通过进行机械加工实训教学改革,采用多种教学手段,灵活教学;丰富加工内容;更换丰富加工材料等对策减少了车刀的磨损报废率,节约了大量的实习成本的同时提高了学生操作动手能力。 Mechanical processing training is an important part of the mechanical teaching process. Machining training courses include: induction machining guide, turning, milling, planing, grinding. One of the most important turning machining, internships account for two-thirds of the entire internship. In the turning process of the tool wear and tear scrap problem is very serious. Through the teaching of mechanical processing training reform, using a variety of teaching methods, flexible teaching; rich processing content; the replacement of rich processing materials and other measures to reduce the wear and tear of the turning rate of the knife, saving a lot of internship costs while improving student hands-on ability.
