Abstract

In this article, the influence of drilling modes of laminated chipboard on cutting power is investigated. It was found that an increase in the feed rate from 1 to 6 m/min leads to an increase in power consumption by 14%. To determine the optimal technological modes that meet modern requirements for quality and productivity, several experiments were conducted. The object of the study was the technological modes of drilling laminated chipboard, namely the feed rate varying from 1 to 6 m/min and the rotation speed of the tool from 1000 to 2000 min–1. These results can be useful in the process of optimizing production processes, improving product quality and reducing energy costs. The main purpose of the study was to conduct an experiment on a CNC machine. This experiment is based on the study of the dependencies of technological modes on the state of the hole edge and the energy consumption of the drilling process of wood materials. The main achievement of this experiment is to ensure the required quality of the process with high productivity and optimal energy consumption. The method of carrying out the work – in the course of the work, experimental studies were carried out, as a result of which real dependences of technological regimes on quality and energy consumption were obtained. Experiments were performed where mathematical planning methods were applied to create a model of the drilling process, taking into account quality and strength. As variable factors, the size of the feed rate, feed per tooth and tool diameter for each cutter were chosen.
