The purpose of this study is to develop a twin wheel creep-feed grinding machine using continuous dressing to machine precise axisymmetric turbine blades that have been difficult to machine using a conventional creep-feed *** order to develop such a machine,3D-modeling and machine simulations were performed and a twin wheel creep-feed grinding machine was ***,the axisymmetric precision of the machined workpieces through practical machining was evaluated and the quality of the continuous dressing effect of the developed machine was *** addition,experimental considerations for a proper dresser-to-wheel speed ratio and proper feed rate of the dresser were carried *** a result,a twin wheel creep-feed grinding machine with continuous dressing is developed through machine simulation,manufacturing and performance *** condition for the dresser feed rate is 0.3μm/*** cases of large dressor-to-wheel speed ratio,grinding efficiency can be enhanced,but the surface roughness shows a conflicting *** twin wheel creep-feed grinding machine has satisfactory appraisal with regard to surface roughness,flatness,and *** surface roughness below 0.1μm can be obtained for the blade of ***,in order to perform precise machining,it is necessary to improve the structure of the twin wheel creep-feed grinding machine.
