汽车缸盖淬硬钢模具结构复杂，型腔表面复杂。在冲压过程中，局部结构承受着比型面更高的挤压应力，往往造成局部磨损甚至开裂。根据模具各部分的特点，采用多硬度拼接工艺，保证了模具的使用寿命。多次切入所产生的冲击载荷，往往导致整个切削过程中切削力的不稳定。降低了模具表面的加工质量。针对球头铣刀在模具拼接区的加工过程，分析了刀具与工件接触瞬间的冲击力。建立了考虑影响因素的瞬时切屑厚度模型和用系数标定切削状态的状态模型。最后，得到了拼接区铣削力的预测模型。以单硬度和多硬度拼接的模具淬硬钢Cr12MoV为例，通过切削力测量实验对模型进行了验证。实验和仿真结果的平均预测误差在10%以内，证明了该模型的准确性。结果表明，该模型对汽车模具覆盖件拼接区的实际加工具有一定的指导意义。
The structure and the cavity surface hardened steel mold of automo bile cover is very complex. In the stamping process, the local struc ture bears higher extrusion stress than the type surface, which often causes local wear and even cracking. The process of multi hardness.splicing joint is applied to ensure the service life of the die according to the features of each part of the mold. The impact load caused by the repeatedly cut-in which always leads to the instability of cutting force in the whole process. The machining quality of the mold sur face is reduced. Aiming at the machining process of the ball-end milling cutter in the mold splicing area, the impact at the moment of contact between the cutter and the workpiece is analyzed. The instantaneous chip thickness model that considers impact factors and the state model that calibrates the cutting state by coefficients is established. Finally, the prediction model of the milling force of the splicing area is obtained. The model is verified based on the machining cutting force measurement experiment in the case of die hardened steel Cr12MoV with single hardness and multi-hardness splicing. The average prediction error of experiments and simulation results is within 10%, which proves the accuracy of the model. The results show that the model has certain guiding significance for the actual processing of the splicing area of automobile mold cover parts..
