整体叶盘扭曲叶片型面加工至设计要求之前,毛坯的叶间通道加工是不可缺少的工艺。针对整体叶盘多通道电解加工三轴运动的特点,先将叶片理论型面的参数转换成整体叶盘的叶间通道的参数,再利用最小二乘法生成通道型面的拟合直线,进一步确定管状工具的运动位置。工具的运动轨迹是三轴组合运动的结果,根据工具的运动状态逆向推算即可获取联动三轴各自的加工参数。最后在整体叶盘多通道电解加工机床上开展试验研究。试验表明,运行上述参数可以加工出符合要求的叶间通道。
The entire leaf disc distortion of the blade profile to the design requirements before the rough leaves of the channel processing is an indispensable process. According to the characteristics of three-axis movement of multi-channel electrolysis processing of leaf disc, the parameters of the theoretical profile of the blade are first converted into the parameters of the leaf channels of the whole leaf disc, and then the fitting line of the channel profile is generated by the least squares method, Tubular tool movement position. Tool trajectory is the result of three-axis combination of movement, according to the inverse kinematics of the tool can be obtained from the linkage of the three-axis processing parameters. Finally, the whole leaf disc multi-channel electrolysis machine tool to carry out experimental research. Experiments show that the above parameters can be run to meet the requirements of the inter-leaf channel.
