Method and device for tapping engine component to orient spark plug

The disclosure provides a method and device for tapping an engine component to orient a spark plug. A device and method of tapping an engine component to orient a spark plug includes measuring a tap pitch; measuring a first distance; calculating a phantom first tap tooth based on the pitch and first distance; determining a tap rotational offset; calculating a tap rotational starting orientation that is the first location minus the tap rotational offset minus a spark plug offset; rotating a tool head to the rotational starting orientation; positioning the tap; synchronizing a rotating speed ofthe tool head and a feed rate to the tap thread pitch; and operating the tool to cut or form threads in the engine component. 本公开提供了"用于对发动机部件进行攻丝以对火花塞进行定向的方法和装置"。一种对发动机部件进行攻丝以对火花塞进行定向的装置和方法，包括：测量丝锥螺距；测量第一距离；基于所述螺距和所述第一距离而计算假想的第一丝锥齿；确定丝锥旋转偏移；计算丝锥旋转起始定向，所述丝锥旋转起始定向是所述第一位置减去所述丝锥旋转偏移减去火花塞偏移；将工具头旋转到所述旋转起始定向；定位所述丝锥；使所述工具头的旋转速度以及进给速率同步到所述丝锥螺纹螺距；以及操作所述工具来在所述发动机部件中切削或形成螺纹。
