General principles of numerical control programming tool path

Open and coarse: under the maximum load of machine tools, most of the cases should use as large a knife as possible as much as possible, and feed as fast as possible. In the case of the same knife, feed is inversely proportional to the amount of feed. Generally speaking, the load of the machine tool is not a problem. The principle of selecting the knife is mainly based on whether the product’s two-dimensional angle and the three-dimensional arc are too small. After selecting the knife, the knife length is fixed. The principle is that the length of the knife is greater than the depth of the processing, while the large workpiece should consider whether the chuck is interfered.

Light knife: the purpose of light knife is to meet the processing requirements of finishing the surface of the workpiece and reserve proper allowance. Similarly, as long as the knife can be used as soon as possible, because the knife needs a longer time to use the most suitable feed and feed. In the same feed, the larger and faster the transverse knife is, the amount of the feed is related to the smoothness after processing. The size of the feed is related to the surface shape of the surface. In the case of no injury, the minimum allowance is left, the maximum knife, the fastest speed, and the proper feed are used.
