Example Embodiment
[0053] Example 1
[0054] A method for optimizing process parameters of CNC machining. The specific requirements for optimizing the feed rate are as follows:
[0055] First read the CNC tool path file, and divide the prop motion path into many smaller segments, the size of each segment is 0.25 to 0.5 times the tool diameter; then according to the amount of material to be cut in each segment (cutting depth × Chip width×segment length), for each cutting situation encountered (cut-in, radian, cut-out, empty cutting), assign the best feed rate:
[0056] 1) When cutting in, take 0.25-0.5 times the tool diameter distance of the initial cutting area, and set the feed rate to 50%-75% of the normal value;
[0057] 2) In the stable cutting zone, adjust the feed speed according to the amount of cutting material per unit time;
[0058] 3) The last 0.25 times the tool diameter distance in the cutting area is set to retract, and the speed will be 50%-75% of the normal value. According to the state o...
Example Embodiment
[0078] Example 2
[0079] According to the guiding ideology described in embodiment 1, this embodiment specifically uses the optimization module OptiPath of the vericut software to perform program optimization, which reads the CNC tool path file and divides the motion into many smaller segments. If necessary, according to the amount of material to be cut in each segment, the software assigns the best feed rate for each cutting situation encountered. Then it generates a new tool path, the new path is the same as the original path but the feed rate is improved. In areas where a small amount of material is cut, Optipath increases the feed rate. When more material is cut, it reduces the feed rate. This prevents the tool from breaking and prevents the machine from exceeding its horsepower. Where possible, a similar high feed rate is maintained, but compared to a situation where the feed rate is slightly reduced for each pass, the software provides greater cutting efficiency and req...
