This paper reports effects of external hydrostatic pressure on machining properties of hard-brittle materials. Experiments for this study utilized a specially designed machining device, and surface turning tests were conducted and machining force were measured with for (4) hard-brittle materials (i.e., silicon, soda glass, quartz glass and quartz) under pressure of 400 MPa and zero MPa. Traces of machining on these specimens were examined with microscopes to evaluate the effects of hydrostatic pressure on machining defects. The results of the experiments show that hydrostatic pressure is efficient to minimize machining defects and it causes increase of machining force. Cutting force was also measured on soda glass. Results indicated increase of cutting force and friction angle under high hydrostatic pressure.

本文报道了外部静水压力对硬脆材料加工性能的影响。本研究的实验采用专门设计的加工装置，对（4）硬脆材料（即硅、钠玻璃、石英玻璃和石英）在400 MPa和400 MPa的压力下进行表面车削试验并测量加工力。零兆帕。用显微镜检查这些样本上的加工痕迹，以评估静水压力对加工缺陷的影响。实验结果表明，静水压力可有效减少加工缺陷，并导致加工力增加。还在钠玻璃上测量了切削力。结果表明，在高静水压力下切削力和摩擦角增加。
