摘要
企业要在当前市场需求多变,竞争激烈的环境中生存和发展就需要迅速地更新和开发出新产品,以最低价格、最好的质量、最短的时间去满足市场需求的不断变化。而普通机床已不适应多品种、小批量生产要求,数控机床则综合了数控技术、微电子技术、自动检测技术等先进技术,最适宜加工小批量、高精度、形状复杂、生产周期要求短的零件。当变更加工对象时只需要换零件加工程序,无需对机床作任何调整,因此能很好地满足产品频繁变化的加工要求。
如果将机床设备全部更新换代,不仅资金投入太大,成本太高,而且原有设备的闲置又将造成极大的浪费。所以最经济的办法就是进行普通机床的数控改造。采用数控改造技术,不但可以使改造后的机床满足了技术发展的需要,提高了生产率和产品精度,增大了设备适应能力和型面加工范围,还可以弥补定购新的数控机床交货周期长的不足。所以采用此方法对中、小型企业来说是十分理想的选择。
CA6140型车床具有性能良好、结构先进、操作轻便等特点,在我国机械制造行业中使用非常广泛。本设计就取其为例,主要介绍其数控化改造的方案、以及改造部位的选型与设计计算。

Abstract
The enterprise must be changeable in the current market demand, competes in the intense environment the survival and the development needs rapidly the renewal and the development new e into the market the product, by the lowest price, the best quality, the shortest time satisfies the market demand the unceasing change. But the ordinary engine bed unsuitable multi- varieties, the small volume production request, the numerical control engine bed synthesized the numerical control technology, the micro electron technology, the automatic detection technology and so on the advanced technology, most is suitable processes the small batch, the high accuracy, the shape plex, the production cycle requests the ponents. When change processing object only needs to trade ponents processing procedure, does not need to make any adjustment to the engine bed, therefore can satisfy the product frequent change well the processing request.
If engine bed pletely renewal, not only fund investment is too big, the cost is too high, moreover the original equipment will leave unused creates the enormous waste. Therefore the most economical means are carry on the ordinary engine bed the numerical control transformation. Use the numerical control transformation technology, not only was allowed to cause the transformation of the engine bed to meet the technological develo
