【摘要】 二次及多次曲线、曲面的加工在一些特殊零件的制造中经常会出现,而在一般的数控机床的指令系统中,往往只有普通的直线与圆弧插补指令,在一些高级的数控系统中也仅包含一些简单的二次曲线插补指令(如抛物线插补),但是这些指令并不能直接用来编制复杂曲线与曲面的加工程序。这里针对宏指令的多样性与灵活性,对数控系统的指令系统进行二次开发,为解决复杂曲线、曲面的加工难题提供了一种可行的途径。更多还原

【Abstract】 The process of the conic and the compiex curved surface usually appear in the manufacture of some special components.But.generally,in the command system of the numerically controlled machine,there are only the ordinary straight line and the circular arc inserts instructions,in some advanced numerical control systems,they contain some simple conic sections inserts instruction(for example parabola inserts),but these instructions cannot use to work out the complex curve the workpiece program of the curved surface directly.This article mainly focuses on the multiplicity and and the flexibility of the macro instruction and carries on a secondary development to the command system of the numerical control system.it has provided one feasible way for the solution of processing difficult problems on complex curve and the curved surface.更多还原
