OPTIMIZATION OF THE PROCESS OF PROCESSING HOLES WITH A TOOL ASSEMBLY REAMER

Currently, scientific and technological progress is associated with the increasing importance of manufacturing technology in the creation of new products. The constant increase in the range of manufactured products, shortening the time for changing production facilities, increasing the complexity of part designs, and increasing the requirements for accuracy and surface quality implies an increase in the volume of blade processing operations, among which hole processing operations occupy a particularly prominent place. This article is devoted to optimizing machining operations to ensure that the finished part is of the required quality at a minimum cost of processing. The effectiveness and expediency of the widespread use of scientifically based optimization methods for the analysis and processing of information, in particular, for the research and optimization of various technological processes of metalworking, is shown. An increase in the efficiency of the hole processing process with a chisel assembly with a rigid attachment without vertex teeth was achieved using a mathematical model solved graphically. Technical limitations have been selected and calculated, and a graphical representation of the machining process with a chisel assembly with without vertex teeth for structural steel (Steel 45) has been constructed. Optimal modes (rotation speed and feed rate) of hole processing have been determined, taking into account all technological, structural, organizational and production conditions. Keywords: reamer, cutting, strength, precision, rigidity, roughness, feed, rotation speed.
