Characteristics of nc lathe machining process principle

Both ordinary lathe and CNC lathe processing, the part that will be processed before machining process analysis, drafting processing scheme, determine the machining lines and content, select the appropriate cutting tools and cutting parameter, design suitable fixture and clamping method. Especially in the numerical control lathe processing, processing technology formulation is more important than ordinary lathe, also want to more detailed, because in ordinary lathe processing, make the process card, the operator according to the machining process, some problems in the processing, such as, As in the inner hole machining, cleaning iron congestion, you stop) Adjustments, flexible processing, will not be affected by too much, and numerical control lathe is different. CNC lathe is controlled by program instructions, machining process is automated, every data, the processing route, cutter, cutting dosage is unreasonable, can cause the workload multiplied, even heavier and so on parts machining from the clamping to complete each work step is very clear, every worker to refine the step change of cutting, cutting dosage, feed lines, etc. More detailed questions. The workpiece machining process design is the preparatory work before, it must be finished before the programming work, only after determine the process design, programming is based on and through the first processing inspection and correction. Thoughtless process is one of the main cause of nc machining error, therefore, the programmer must pay attention to the process design will do a good job first, for some balance of data ( Such as cutting depth, cutting tool cutting effect, etc. ) In such a hurry, can make the necessary testing, programming is tend to attend. Numerical control lathe in machining process and principle of ordinary lathe machining process on basic same, but as a result of the numerical control lathe, by contrast, in the processing performance, the control method has its advantages and disadvantages, thus has its characteristics. First, numerical control lathe machining process is complicated than ordinary lathe machining process content. CNC lathe usually arrange more complex process or on the ordinary lathe machining is difficult to control the process, such as arc surface connection, taper thread and steps, concave surface, etc. , so, in the aspect of processing difficulty relatively increased. Second, the numerical control lathe processing program than ordinary lathe process planning establishment of complex. This is because in the engine lathe processing, many processing need not consider problems ( Such as chip removal, tool change, positioning clamping) In nc processing technology, we can not ignore, these problems in the processing of ordinary lathe can be adjusted at any time by the operator according to the situation, and numerical control lathe in machining adjustment is more intricate.
