Abstract
- Due to the features of Waspaloy, such as high-temperature resistance, easy to hardening, low thermal diffusivity, and low thermal conductivity, the milling cutter for internal threads suffers from serious wear. Particularly, the milling cutter for internal thread with a small diameter restricts the application of milling technology to Waspaloy threads. Based on the cutting flow stress control theory and the cutter wear control theory, a three-dimensional wear calculation model for milling cutter with small diameter internal thread was established. SEM was used to obtain the surface morphology and wear of the machined thread milling cutter, compared with the calculated results; the accuracy of the calculated results is verified. It employed the calculation model to study the variation law of tool wear under different milling parameters and front angle. The better milling parameters and front angles were obtained. In combination of the calculation results and the actual processing requirements, it is recommended: rotation speed, 600–900 r/min; revolution speed, 5–10 r/min; milling depth, 1/2–3/4 of the height of thread teeth; front angle, 5°–10°. And it is significant for the reduction of cutter wear and reasonable design and application of milling cutter for internal thread with a small diameter. [ABSTRACT FROM AUTHOR]
