Optimization of diamond drilling using extreme experiment design

The results of experimental studies on the choice of the optimal characteristics of diamond drills and modes of machining holes with a diameter of 1 - 70 mm in brittle solid non-metallic materials: quartz, ceramics, glass, glass, are presented. To obtain experimental-mathematical models at the screening stage, a randomized experimental design was used - a semi-replica from a full-factor experiment 23, and at the main stage - a second-order orthogonal compositional plan of type 35. The diamond drilling process was optimized using the simplex method. Comparison of the calculated values ??and experimental data showed a good adequacy of the results obtained.
