THE USE OF HIGH-PERFORMANCE TOOLS AS A METHOD OF REDUCING THE TIME OF MANUFACTURING PARTS ON CNC MACHINES

Abstract

The article reveals the principles of using a high-performance tool as a method of reducing the time of manufacturing parts on machines with numerical program control. It is noted that high-speed cutting technology using modification, optimization and replacement princes or a combination of processing steps can increase energy and resource efficiency in the overall process, mainly by reducing production time. It is proposed to abandon pre-processing using high-speed cutting technology based on high-performance tools, and immediately make the parts finally hardened. A modified chain of technological production has been formed using a high-performance tool as a method of reducing the time of manufacturing parts on CNC machines. Two production cycles were selected: the batch production cycle with mandatory sequential operations and the batch production cycle using high-speed cutting technology based on a high-performance tool. The operating time of each line on a batch of parts from 1 to 150 pieces, with a step of 25 pieces is analyzed. The ratio of the time of production of parts depending on the volume of the batch of parts produced, taking into account the performance of the cycle of production of the batch of parts using high-speed cutting technology based on high-performance tools and time spent on the production cycle of parts with mandatory sequential operations. It is emphasized that the use of high-speed cutting technology is advantageous in terms of production, which is often reconfigurable, given the full time spent on debugging the manufacturing process of the part finally hardened. It is proved that in the implementation of the cycle of manufacturing a batch of parts with mandatory sequential operations, the value of extensive use of equipment tends to the limit value, which depends on the time spent on pre-workpiece and production cannot be completely eliminated.
