摘要
Abstract
As to the current technology,the gas turbine disk groove is usually processed by broaching,which has great advantages in process quality and efficiency.However,the price of broaching tools has remained high,so there are great difficulties in cost control in small-scale production.Aimed at it,a milling method for disk groove of a gas turbine was proposed.The cutting resistance was reduced by scheme optimization of milling tools,so the dimensional accuracy and smoothness of the groove could be ensured,meanwhile,the usage costs of the tools was greatly lowered.Based on the self-centering structure of the Hertz tooth on the end face of the disk,a disk tooling was designed as a transition device between the turntable and the disk,thereby,accurate positioning of the disk clamping was realized.Meanwhile,the meshing of the Hertz tooth was used to transmit the torque of the turntable,so the machining division was verified.In addition,a circular grating monitoring device was installed to realize real-time monitoring of disk division,ensuring the process accuracy of the groove division.The research results can provide reference for the groove milling of large-scale disks.关键词
