数控编程是数控加工准备阶段的主要内容之一，大连数控加工通常包括剖析零件图样 ，确定加工工艺历程
；盘算走刀轨迹，得出刀位数据
；编写数控加工程序
；制作控制介质
；校对程序及首件试切。

手工编程是指编程的各个阶段均由人工完成。利用一般的盘算工具，通过种种三角函数盘算方法，人工进行刀具轨迹的运算，并进行指令体例。

这种方法比较简单，很容易掌握，适应性较大。使用于非模具加工的零件。

Numerical control programming is one of the main contents in the preparation stage of numerical control machining. Dalian numerical control machining usually includes analyzing part drawings and determining the machining process; Calculate the tool path and obtain tool position data; Write CNC machining programs; Create control media; Proofreading program and first piece trial cutting.

Manual programming refers to the process where all stages of programming are completed manually. Using general computing tools and various trigonometric calculation methods, manually calculate the tool path and develop instructions.

This method is relatively simple, easy to master, and adaptable. Used for non mold processed parts.
