From the viewpoint of project,parameter drawing:Offer a large number of figure mask works,daily CAD figure only needs to input the parameter and can be produced automatically; Offer assisting the drawing menu of CAD,the ones that let the figure revised and drawn and changed are simple.To put it briefly draw support from the software with special function,can input the characteristic parameter of the figure that complete reality ask,calculate the ocular necessary figure of output through computer!Programme the work load very big by hand,apt to make mistakes,as to the simple part,it can usually be competent to programme by hand.Some parts or space curved surface parts with complicated form,it is very enormous to programme and work,it is very much tedious to calculate,cost it too long,so has developed the automatic programming system of the computer,finish numerical control and process the automatic programming of the procedure.
Automatic programming is called the computer (the or programming machine) and assisted programming too.I.e.the finishing by computer in part or in whole big of procedure documentation.Such as finish coordinate value calculate,write part process procedures sheet,etc.,even can help,carry on craft punish sometimes.Automatic programming procedure appeared to edit also can carry on cutter sport figure of orbit check through computer or autoplotter,programming personnel can audit program correct in time,and revise in time.Automatic programming has lightened programming personnel's labour intensity greatly,dozens of times are to hundreds of times to raise the efficiency,solved the programming difficult problem of programming a lot of complicated parts that can't be solved by hand at the same time.The more complicated the job surface form is,the more tedious the craft course is,the more obvious the advantage of automatic programming is.The main type of automatic programming is as follows,language programming of numerical control (such as APT language),interactive programming of figure (such as CAD/CAM software),pronunciation type automatic programming and model type automatic programming of material object,etc..
This software is specially used in the parameter drawing of the level cam and turn into numerical control to process codes.Can demand to produce the curve outline of the cam according to users.Produce the curve by the way of approaching sharply as to the non- round geometirc form!
