Abstract
Naissance that 20 century middle period few technique is with the few machine the bed scribe to produce with control coming of a brand-new ages of realm.
The science technique bring upped with rate of production to the quantity of the machine product with the quick development of the social productivity more and more high request.The automation that machine process the craft process one of the most important measure of becoming to realizes the above requests.It can not only increase the product quantity,increase the rate of production ,lower the production cost ,and can be still biggest ameliorative production of labor term.
Work process that few machine the bed will process the spare parts several why the information proceedswith the craft informations the arithmetic figure handle,then operation allly the step have with knife with of the work piece the code for of opposite moving,and entering giving the speed waiting all using the arithmetic figure mean.But few of the economic types then reform the logarithms achine bed contain new request.
Namely still want the superior etc.of particular about and economic,dependable,function under not changes originally the function’s prior condition.Therefore,at reform at the same time ,and as far as possible don’t change original construction.
Key words: Rate of production Economic type Dependable
