螺旋铣孔具有铣削力小、加工质量好、加工效率高的优点。Al/SiC是典型难加工材料,铣削过程中铣削力和转矩大。铣削力和转矩大会造成刀具及其工件严重变形,铣削力和转矩在很大程度上也会影响零件表面质量和使用性能。应用螺旋铣孔技术加工Al/SiC材料孔,研究了切削速度和进给率对铣削力和转矩的影响规律。实验结果表明切削速度和进给率对铣削力和转矩有重要影响。铣削力和转矩随切削速度增大先增大后减小。铣削力和转矩随进给率增加而增加。并从切屑几何形状、加工硬化、热软化、材料微观结构方面分析了铣削力随切削参数的变化规律。从铣削力和加工效率方面考虑实际生产中可以增加切削速度,适当降...

The spiral milling hole has the advantages of small cutting force, good processing quality and high processing efficiency. Al/SiC is typical difficult-to-machine material with large milling force and torque in helical milling. Causing the cutting tool and the workpiece deformation seriously, high cutting force and torque affect parts surface quality and using properties to a great extent. The holes of Al/SiC material were processed using spiral milling technology. This paper presents the impact of the feed rate and speed on pro-cessing forces and torque during spiral milling hole. It was found...
