DESIGN AND DEVELOPMENT OF RADIUS AND FACE DRESSER FIXTURE FOR THE GRINDING WHEEL

Mechanical Engineering

Grinding is the most important processes in manufacturing of many precision components thanks to its unique abilities in making well-qualified parts. The performance of the grinding depends on many factors among which dressing is the most influential one. Dressing forces may affect directly the geometrical accuracy of the profiles made during the grinding operation. In addition, the wheel topography which is determined by dressing parameters influences the work piece surface quality and grinding forces and temperature. In this paper, the new developments in dressing process, radius assisted dressing and dressing by T-Dress, are addressed the grinding processes usually considered as the finishing process in the manufacture of components with high accuracy and surface quality. The efficiency of grinding process is largely affected by conditioning and dressing of the grinding wheels owing to the topography which is created on their surface [1]. In this paper, use of ultrasonic vibrations in dressing process and making new structures on the grinding wheel surface are introduced to approach an efficient grinding process. The use of the ultrasonic assistance results in significant improvements in machining processes.
