The paper investigated the reliability of the cutters with natural diamond single crystals with small oblique turning aluminum alloys. The main aim is to quantify the reliability (probability of failure) single crystals of diamond cutting tools when changing the cutting speed and the angle of the cutting edge of the blade at an oblique turning of aluminum alloys.
Research in cutting was carried out on high-precision lathe TPK-125VM stepless spindle speed main motion from 100 to 2400 rev/ min. Experiments were conducted in face turning, the processed material - aluminum alloy AMg6.
We use automated system for studying the process of cutting included universal dynamometer UDM - 100 design) and developed by us tenzoamplifier "Topaz" and the ADC 1406 ADA firm HOLIT Data Systems and PC.
The results of the study effect of cutting force and cutting speed on the theoretical probability of destruction diamond single crystals at different cutting speeds and angles of the cutting blade. To calculate the probability of destruction cutter was used mathematical model developed at the V. Bakul Institute for Superhard Materials by professor Devin L. and automated system for measuring cutting forces in turning using software «PowerGraph».
