DEVELOPMENT OF A CONTROL AND MONITOR SYSTEM OF GRINDING WHEEL SPEED IN THE 1Б811 RELIEVING LATHE
Abstract
1Б811 relieving lathe which is a specialized machine with high precision is
manufactured by the Soviet Union. This machine is used to machine the cutting
tools such as the modular disc milling cutters, the modular lug cutters, the gear
cutting cutter, the thread cutting cutters, etc. Using 1Б811 lathe, the accuracy of
grinding processes are quite high. However, the grinding wheel speed has not
controlled to adjust the cutting speed for optimization problem of the machined
surface quality. A control and monitor system was developed to adjust the
grinding wheel speed in the 1Б811 lathe. A new electric drive system using an
inverter and an ARM STM32F103 microcontroller was designed to replace the old
drive system. The test results showed that the new drive system can control the
speed of the grinding wheel to meet the requirements for optimization problem
of the machined surface quality.
