Through its cutting test and examining its wearing proces s,the results show that the life of cutter coated with diamond film is markedly higher than non-coated cutter,and the wearing process of diamond-film-coate d cutter is from the micro-cracking of the film at the beginning to the gradual dropping in the end.
Based on a lot of experimental results, liquid explosive linear shaped charge cutter with the best structure paramenters is designed. Some of the best conditions available is determined as the basis of practical applications.
Cutting force model for a small-diameter helical milling cutter
In the milling process, the major flank wear land area (two-dimensional measurement for the wear) of a small-diameter milling cutter, as wear standard, can reflect actual changes of the wear land of the cutter.
By analyzing the wearing characteristics of the cutter, a cutting force model based on the major flank wear land area is established.
The cutting force model for the helical milling cutter is validated by experiments.
Thus, the cutting force model established in the research can provide a theoretical foundation for monitoring the condition of a milling process that uses a small-diameter helical milling cutter.
