In CNC machining, one sentence solves the judgment of thread rotation, spindle forward and reverse, and circular interpolation. In the junior high school physics tutorial, the relationship between the direction of the magnetic induction line excited by the current is usually judged by the Ampere's law or the right-hand rule. In fact, this rule is often used in CNC machining to determine the direction of thread rotation, spindle forward and reverse, and arc interpolation commands.
Among them, the thread rotation direction is left-right rotation. As shown in the figure, the right-hand thread is an example. In most cases, the direction in which the four fingers are bent indicates the direction of rotation of the thread, and the thumb indicates the direction of movement of the nut. For example, to open and close the cap of a mineral water bottle, you can try it out with your right hand!
The spindle of the CNC machine tool has positive and negative rotation, and the tool post is divided into front and rear. Some people can't figure it out. In fact, we can also use the right hand to make judgments, and it is not easy to be confused. As shown in the figure, the tool post is a front tool post, the direction of spindle rotation is the forward rotation of the spindle, and the command used is M03. What if the tool holder is a rear tool holder? How to judge the direction of the main shaft forward rotation? In fact, the reason is very simple. The tool is mirrored about the Z axis, that is, the workpiece, so the rotation of the spindle must be the opposite.
According to my personal experience, I use the right-hand rule to make the judgment: CNC lathes are all based on the rear tool post, the thumb is pointing to the negative direction of the Z axis of the CNC machine tool, that is, the direction of the workpiece, and the four fingers are bent in the direction It is the forward direction of the spindle, clockwise, M03.
Also in the CNC milling machine, the thumb is pointing to the negative direction of the Z axis, and the spindle rotates positively, that is, the direction of rotation of the milling cutter is clockwise in the XOY plane, using M03. One sentence: Use the right-hand rule to control the large The direction of the thumb and the bending direction of the four fingers are the G02G03 selection of thread rotation, spindle forward and reverse, and arc interpolation, which can be solved easily.
