The path of the tool is the trajectory of the tool in the whole process. It not only includes the content of the step, but also reflects the sequence of steps. The route is one of the basis for writing the program. The following points should be noted when determining the route:
1. Seek the shortest machining route and reduce the emptying time to improve machining efficiency
For example, the hole system on the part shown in Fig. 1a is processed. The running path of the figure b is to machine the inner ring hole after the outer ring hole is processed. If you use the c-route route, you can save nearly double the positioning time.

In metal cutting, hole processing is the most common process. In hole processing, drill drilling is the basic process.
When drilling, if the hole on the workpiece is very deep, carbide deep hole drills should be used at this time.
Specially used for processing deep hole drills, deep hole drills. In processing, holes with an aperture ratio greater than 6 are usually called deep holes. Due to the poor rigidity of the drill rod, it is difficult to remove heat and debris during deep hole drilling, and it is easy to bend and vibrate. Cooling and cooling systems are usually used to solve cooling and chip removal problems. In the automotive, mold and aerospace industries, deep hole drill bits are very popular.
