Do you understand the general rules of the tool path in cnc machining?

The general rules of the tool path in cnc machining are as follows:

1. Open rough

Under the maximum load of the cnc processing machine tool, in most cases, the largest possible knife, the largest possible feed amount, and the fastest possible feed should be selected.

In the case of the same knife in cnc machining, the feed is inversely proportional to the amount of feed. Under normal circumstances, the load of the cnc machine tool is not a problem. The principle of tool selection is mainly based on whether the two-dimensional angle and three-dimensional arc of the product are too small. After the tool is selected, the length of the tool is determined. The principle is that the tool length is greater than the processing depth. When adding parts to a large machine, it is necessary to consider whether the chuck interferes.

2. Light Knife

The purpose of cnc machining light knife is to meet the processing requirements of the surface finish of machined parts and reserve an appropriate margin. In the same way, the light knife chooses the largest possible knife and feeds as fast as possible, because the fine knife takes a long time, use the most suitable knife and feed.

Under the same feed in cnc machining, the larger the lateral feed, the faster the feed. The feed amount of the curved surface is related to the smoothness after processing. The margin, the largest knife, the fastest speed, the appropriate feed.
