利用高精度红外摄像装置，考虑刀具内的温度分布，对建立的正交化加工过程的有限差分温度预测模型进行了验证。热实验是用两种不同的材料进行的：Al 7075，AISI 1050，具有两种不同的刀具几何形状；具有6度和18度前倾角的刀片，用于不同的切割速度和进给速度。利用红外摄像装置进行热实验。将高精度红外热测量结果与有限差分温度模型的结果进行了比较，考虑了刀具-切屑界面区的最高温度和平均温度以及刀具表面的温度分布。刀具-切屑界面最高温度随切削速度和进给速度的增加而升高。刀具-切屑界面最高温度与刀具前倾角的关系不明显。实验结果与仿真结果吻合较好。(C)2007 Elsevier B.V.保留所有权利。
The validation of a previously developed finite difference temperature prediction model is carried out for orthogonal machining process with a high precision infrared camera set-up, considering the temperature distribution in the tool. The thermal experiments are conducted with two different materials; Al 7075, AISI 1050, with two different tool geometries; inserts having a rake angle of 6 degrees and 18 degrees, for different cutting velocities and feedrates. An infrared camera set-up is utilized for the thermal experiments. The results of the high precision infrared thermal measurements are compared with the outputs of the finite difference temperature model, considering the maximum and the mean temperatures in the tool-chip interface zone and the temperature distributions on the tool take face. The maximum tool-chip interface temperature increases with increasing cutting velocity and feedrate. The relationship between the maximum tool-chip interface temperature and the rake angle of the tool is not distinctive. The experimental results show good agreement with the simulations.
