The rational use of CNC machining center tool walker

CNC machining center in the process of high-speed machining, to maintain the smoothness of the load throughout the cutting process, to avoid sudden changes in direction, and also to avoid sudden changes in direction when reducing the amount of feed or tool stop. So what strategies should be followed during CNC machining? The following is introduced by me.

When the tool path is determined, the CNC machining center should be dominated by smooth milling during high-speed machining to reduce tool wear and improve machining accuracy. According to the principle of shallow cutting and small layer depth of layering, a reasonable layering route is used to achieve the rationality of machining and smoothness of load. In the corner should increase the circular arc walking tool, to prevent the corner speed vector direction of the sudden change, to avoid sharp changes in the tool load.

In the CNC machining center plane two-way cutting processing, can be in the adjacent two rows of tool trajectory between the additional arc transfer, in order to form a smooth lateral shift. In the space two-way cutting processing, you can use the space arc transfer, space inside the arc transfer, space outside the arc transfer and "golf" type transition transfer and other forms of extended transition, which not only ensures the smoothness of the tool trajectory, but also effectively avoid the phenomenon of turning hard bend between the two lines, this transfer method is commonly used in a variety of Curved surface high-speed milling.

In order to avoid the CNC machining center in the shape of the contour of the normal direct feed and retreat, should be used spiral, arc and diagonal way into and out of the tool, to ensure smooth into and out of the tool, the steep wall surface and non-steep wall surface finishing, in order to prevent sharp changes in cutting load, CNC machining center to apply different methods of steep wall surface and non-steep wall surface separate processing, can improve the cutting speed, while making the roughness of the surface of the part uniform.
