刀具长度偏置 (G43/G44/G49) FANUC 0-MD的G代码命令及举例
2024年3月17日 · G43: 把指定的刀具偏置值加到命令的 Z 坐标值上。 G44: 把指定的刀具偏置值从命令的 Z 坐标值上减去。 G49: 取消刀具偏置值。 在设置偏置的长度时,使用正/负号。 如果改变了 (+/-) 符号, G43 和 G44 在执行时会反向操作。 因此,该命令有各种不同的表达方式 ...
G43 G44 and G49 tool length compensation - Blogger
2014年12月12日 · G44 is a rarely-used alternative to G43. It tells the control to begin applying tool length compensation, by subtracting the current length offset from all Z axis positions. In this scheme, larger length offset numbers identify shorter tools (as if they were measured from the table up rather than from the spindle down).
加工中心G43和G44指令怎么使用,在加工中心上又该怎么设置_百 …
典型的指令格式为G43Z_ H_ 或G44Z_ H_。 其中G43指令加补偿值,也叫正向补偿,即把编程的Z值加上H代码指定的偏值寄存器中预设的数值后作为CNC实际执行的Z坐标移动值。 相应的,G44指令 减去预设的补偿值,也叫负向补偿。
G43 and H codes: Tool Offsets – Support for CNC
G43 is the code which directs the CNC controller to find the tool length for the tool that is about to do some cutting. In its simplest use, the TLO is found by jogging the spindle with tool from the machine home Z-position to the part Z-zero position, as shown on the far left in …
