Abstract: PURPOSE: A high speed machining method is provided to develop a test sample for showing performance of a high speed machine and to estimate the influence of cutting depth, feeding speed, and RPM of a main shaft on surface roughness and machining error by using steel. CONSTITUTION: For a steel machining test of a high speed machine, the influence of surface roughness and a Z-axis machining error is analyzed by two-way layouts with changing cutting depth, feeding speed, and RPM of a main shaft. As a result, the cutting depth, feeding speed, and RPM of the main shaft have no effect on the Z-axis machining error. The influence of each factor is decreased for surface roughness less than aluminum machining. Wear of tools caused by machining heat-resisting low alloy steel has a great effect on each factor. The cutting force is related closely to the surface roughness. Favorable surface roughness is obtained by reducing the cutting force.
