霸刀分享-数控编程常用指令
数控编程常用指令可以分为很多类，不同类型的指令有着不同的功能，下面我来详细说说：
快速定位指令G00：能让刀具以各轴设定的最高允许速度，从当前位置快速移动到指定位置，移动时不进行切削，一般用于刀具快速接近或离开工件。比如要把刀具快速移动到工件上方准备加工，就可以用G00指令。
直线插补指令G01：使刀具以设定的进给速度沿着直线轨迹进行切削加工，通过指定起点和终点坐标，以及可选的F参数来控制进给速度。像加工一个长方体的棱边，就会用到G01指令。
圆弧插补指令G02、G03：G02是顺时针圆弧插补，G03是逆时针圆弧插补。刀具会以设定的进给速度，沿着相应方向的圆弧轨迹进行切削加工。例如加工一个圆形的轮廓，就需要用G02或G03指令。
刀具半径补偿G40、G41、G42：在零件轮廓加工中，由于刀具总有一定的半径，刀具中心的运动轨迹与所加工零件的实际轮廓并不重合，就需要进行刀具半径补偿。G40是取消刀具半径补偿功能，G41是在相对于刀具前进方向左侧进行补偿（左刀补），G42是在相对于刀具前进方向右侧进行补偿（右刀补）。这样编程时可以不考虑刀具的半径，直接按图样所给定尺寸编程，只要在实际加工时输入刀具的半径就行。
M00：程序暂停，当程序执行到M00时，数控系统会停止所有正在进行的操作，此时操作者可以进行一些必要的操作，比如更换刀具、测量工件等，操作完成后，通过输入相应的指令来继续程序的执行。
M02：程序结束，该指令表示执行完程序内所有指令后，主轴停止，进给停止，冷却液关闭，机床处于复位状态。
M03、M04、M05：M03用于控制主轴正转，M04用于控制主轴反转，M05用于停止主轴的旋转。
F代码：用于设置切削进给的速度，有每转进给量和每分钟进给量两种表示方式。
S代码：用于设置主轴的转速。
这些就是数控编程里比较常用的指令啦，不同的数控系统可能在指令的具体格式和用法上会有一些小差异哦。
Common instructions for numerical control programming
Common instructions for numerical control programming can be classified into many categories. Different types of instructions have different functions. Let me elaborate on them below
Quick Positioning Command G00: It enables the tool to move rapidly from the current position to the designated position at the maximum allowable speed set for each axis. No cutting is performed during the movement. It is generally used for the tool to quickly approach or leave the workpiece. For instance, if you need to quickly move the cutting tool above the workpiece for processing, you can use the G00 command.
Linear interpolation command G01: It enables the tool to perform cutting operations along a linear trajectory at the set feed rate. The feed rate is controlled by specifying the starting and ending point coordinates, as well as the optional F parameter. When processing the edges of a cuboid, the G01 command is used.
Circular interpolation commands G02 and G03: G02 is clockwise circular interpolation, and G03 is counterclockwise circular interpolation. The cutting tool will perform cutting operations along the corresponding arc trajectory at the set feed rate. For instance, when processing a circular outline, the G02 or G03 command is required.
Tool radius compensation G40, G41, G42: In the contour processing of parts, since the tool always has a certain radius and the movement trajectory of the tool center does not coincide with the actual contour of the part being processed, tool radius compensation is required. G40 eliminates the tool radius compensation function, G41 performs compensation on the left side relative to the tool's forward direction (left tool compensation), and G42 performs compensation on the right side relative to the tool's forward direction (right tool compensation). In this way, when programming, the radius of the tool can be disregarded. Program directly according to the given dimensions on the drawing. Just input the radius of the tool during actual processing.
M00: Program pause. When the program reaches M00, the numerical control system will stop all ongoing operations. At this point, the operator can perform some necessary operations, such as changing tools and measuring workpieces. After the operation is completed, the program can continue to execute by inputting the corresponding instructions.
M02: Program ended. This instruction indicates that after all the instructions within the program have been executed, the spindle stops, the feed stops, the coolant is turned off, and the machine tool is in the reset state.
M03, M04, M05: M03 is used to control the forward rotation of the spindle, M04 is used to control the reverse rotation of the spindle, and M05 is used to stop the rotation of the spindle.
F code: It is used to set the speed of cutting feed and is expressed in two ways: feed per revolution and feed per minute.
Code S: Used to set the rotational speed of the spindle.
These are the more commonly used instructions in numerical control programming. Different numerical control systems may have some minor differences in the specific format and usage of the instructions.
