1. Bouncing knife, the tensile strength of CNC cutting tool is not too long or not too large, causing the NC blade to bouncing off. For such things, it is necessary to clarify the specifications of the CNC lathe machining tools: it can be large and short.
2. Improper operation by the operator. This kind of thing must be run with the face milling program, and the feed is as evenly distributed as possible (the side feed and the bottom feed are the same).
3. The milling feed is uneven. (For example, leave 0.5 at the side of the slope and 0.15 at the bottom). When such a thing occurs, the main parameters of milling must be adjusted scientifically and standardly, and the corners with large feeds must be rounded.
4. The key parameters of milling are wrong (such as: standard tolerance is quite large, SF setting is too fast, etc.). At this time, the SF function of the CNC milling machine should be used flexibly, and the operator adjusted the speed to improve the expected effect of the CNC milling machine.
