Knife path planning
The principle of tool selection is to consider whether the two-dimensional angle and the three-dimensional angle are too small. After selecting the tool, the next step is to determine the length of the tool, that is, the length of the tool is greater than the depth of processing, and the big workpiece is concerned about whether the chuck will interfere.
1. Mold opening: under the limit load that the machine can bear, it is recommended to select the largest tool, the largest feed and the fastest feed.
2. Mold smooth knife: the function of the smooth knife is to meet the working surface finish and reserve appropriate allowance for machining requirements. When choosing a light knife, it's better to choose a larger knife to make the time faster. Under the condition of the maximum feed and the maximum feed, the faster the feed is related to the maximum feed and the maximum feed.
