Method for working shaft-like workpiece by numerical control lathe and its control device

Abstract

This invention refers to a method for machining axle like piece by digital controlled machine tool, which features preset mathematics model of virtual work piece in memory of lathe controller, said model having all character section of axle like work piece, the user inputting character parameter of each section of work piece, computer reading out character parameter and selecting preset corresponded character section, calculating and modifying each character section to form worked piece model and cutter route, imitating and displaying working process, modifying cutter route to fit the pattern of worked piece, then making machining.

Description

technical field [0001] The invention relates to a method for machining shaft workpieces on a numerically controlled lathe, specifically, a method and a numerically controlled device for machining shaft mechanical parts on a numerically controlled lathe using group process numerically controlled programs, and is particularly suitable for numerically controlled transformation of ordinary lathes. Background technique [0002] With the improvement of human living standards and the progress of society, people's pursuit of personalization and specialization is becoming more and more common, and the trend of diversification of society's demand for mechanical products is becoming more and more obvious. / There are more and more small-batch products, accounting for about 76-85% of all kinds of mechanical products. There are some contradictions in the traditional organizational model for small batch production: such as: production planning, organization and management are complicated;...

Problems solved by technology

[0003] However, in the traditional CNC machining technology, for each part, it is necessary for the craftsman to compile the machining process first, and then the programmer writes the NC program of the process for cutting. This programming method requires a lot of work for the programmer. Large, programming, input, and debugging are very cumbersome and time-consuming, resulting in a long production cycle and often delaying the delivery date; at the same time, the operator's skill requirements are also high, which is likely to affect the quality of the product

Although there are softwares that can automatically generate NC machining programs, the operator only needs to input the workpiece parameters, and the machine tool control device will automatically generate NC programs, which can solve the above problems, but these softwares are very large. As far as lathes are concerned, many functions of the software are useless, and the price is expensive and uneconomical. Obviously, it is not suitable for the transformation of ordinary lathes with large quantities and wide areas.
