Very often, when the ripper cutter is just milling, the amount of tool eaten is relatively large, which may cause the tool to break or snap the knife. At this time, you can first open the lower tool position or lift the cutter away, or cut the tool outside the material during the day. In short, we must fully consider (consider) this issue (Emerson).

CNC machining CNC lathe feed processing route refers to the path that the turning tool moves from the tool setting point (or the fixed origin of the machine tool) until it returns to this point and ends the processing program, including the cutting path and the tool cutting in, cutting out, etc. Non-cutting idle travel path.

Shenzhen CNC machining has high production efficiency under the condition of multiple varieties and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.

When the processing volume is relatively large, the tool holder is too long and the tool is too small. This situation often occurs (Condition). The processing volume is relatively large, especially when the concentration of cutting is high, it is easy to happen. For example, the light side depth H=50mm diameter 3/4 cutting, we can divide the 25mm secondary processing, and it is not easy to happen. The tool clamp is too long. The length of the tool is very important for processing. The clamp should be as short as possible. It is easy for beginners to ignore this problem (Emerson), and the clamping length of the tool must be marked on the procedure paper.

It is easy to grab a knife when turning a corner. The solution is to clear the corner layer by layer with a smaller knife, and then change the side of a larger knife. Like the semicircular groove with diameter 8 as shown in the figure, if it is directly processed with an R4 knife, the position of the knife is easy to grab the knife. The solution is

   (1) Use R3 to scan the tool path (2) In machining non-standard CNC machining, first use R3 to roughen, and finally use R4 to clear the corner light knife. CNC computer gong processing is an automated machine tool equipped with a program control system. The control system can logically process the program with control codes or other symbolic instructions, and decode it, so as to make the machine tool move and process parts. Also called CNC or numerical control machine tool.
