数控车非圆曲线件的工艺方案处理及程序设计

Processing and Process Design of Non-circular Curve Parts on CNC Lathe

在数控机床进行加工椭圆、抛物线、双曲线等公式曲线的数控程序编制与加工,可采用宏程序。使用变量、算数和逻辑运算及条件转移,使得编制相同的程序更方便、简洁,同时尺寸及形位公差控制更加容易。研究了基于椭圆配合件的数控加工工艺方案设计及数控宏程序编制,有效地利用工艺方案实施配合件的配合精度控制的方法。

Machining ellipse, parabola, hyperbola in NC machine tool of formula curve NC programming and the price, the macro program. Transfer the use of variables, arithmetic and logic operations and conditions, it makes the same procedure more convenient, concise, and at the same time, size and shape and position tolerance control more easily. This paper mainly studies the design and numerical control scheme based on ellipse with NC machining parts macro programming, efficient use of technology implementation method with the precision control of the.
