摘要
为研究TiN涂层刀具切削淬硬H13钢的切削性能,进行了TiN涂层刀具车削加工淬硬H13钢试验。分析了切削用量与切削力、切削温度的关系及涂层刀具磨损机制。研究得出切削速度、切削深度、进给量都对主切削力Fz和切深抗力Fx影响较大,对切削进给抗力Fy影响相对较小;切削速度对切削温度的影响最大;对刀具磨损观察发现刀具的前刀面有明显的月牙洼磨损,刀尖部位出现了微崩刃现象,后刀面出现磨粒磨损。研究结果为生产加工中优化切削用量及提高刀具寿命提供了技术支持和试验依据。
In order to study the performance of cutting H13 hard steel with Titanium Nitride（ TiN） coated cutting tool,cutting tests of H13 hard steel with TiN coated tools are carried out. The influences of cutting parameters on the cutting force,cutting temperature were studied. The wear and breakage mechanism of carbide coated tool wear were analyzed. It is found that cutting speed,depth of cut and feed rate have great influence on the main cutting force Fzand cutting depth resistance Fx,while less effect on feed resistance Fy. Cutting speed has the greatest influence on cutting temperature. Tool rake face has obvious crater wear and the tool tip occurs micro breakage phenomenon,abrasive wear appears on the flank from observed the tool wear. This study results can provide technical support and experimental guidance for optimization of cutting parameters and improvement of tool life in the machining production.
