论数控车床VT-20加工中出现的问题与解决办法VIP免费

论文题目：数控车床 VT-20 加工 L CAR 转向机阀壳的特点摘要文章主要通过本人在上海华迅汽车配件有限公司实习时对数控机床 VT—20 实际操作，以及其在加工 L CAR 转向机阀壳时总结出的一些特点，对其进行简单概要的论述，在这一过程中我对数控机床的操作有了更深一层次的了解和认识。我们都知道数控机床以其精度高、效率高、工序集中、能适应小批量多品种复杂零件的加工等优点，在机械加工中得到日益广泛的应用。精度高：工件公差范围在 2 丝以内。效率高：正常频率下一个工件的加工时间约为 3 分钟。适应力强：能在三小时内更换产品，并加工出符合要求的成品。复杂零件：在做内孔加工对同轴度，倒角等均有较高的要求时，能满足图纸需要。工序集中：能在一台加工中心上完成钻，铰，铣等多步工序。本文将根据上述这些数控加工的特点及其在实际加工中运用结合我在实际操作中遇到的一些问题及解决办法，以及 FUNC 数控系统的一些常用指令等做一些简单，肤浅的介绍和论述。关键词：精度，效率ABSTRACTThe article mainly through myself practises when the Shanghai Huaxun automobile company to the numerical controlengine bed VT - 20 actual operations, some characteristics which byand its when processes L CAR steering unit valve shell summarizes,carries on the simple outline to it the elaboration, I had the deeperlevel understanding and the understanding in this process to thenumerical control engine bed operation. We all knew the numerical control engine bed by its precision high,the efficiency is high, the working procedure centralism, can adaptsmall batch multi- varieties complex components merit and so onprocessing, obtains day by day the widespread application in themachine-finishing. Precision high: Work piece tolerance zone in 2.Efficiency high: The normal frequency next work piece process periodapproximately is 3 minutes. Suitable stress strong: Can replace the product in three hours, andprocesses conforms to the request end product. Complex components: When making the hole processin...
