Abstract The tool geometry is generally of great significance in metal cutting performance. response surface method was used to optimize chamfer achieve reliable and minimum wear slot milling. Models were developed for edge chipping, rake wear, flank wear. adequacy the models verified using analysis variance at a 95% confidence level. Each optimized individually, multiple responses simultaneous...

Surface quality including surface roughness and edge chipping is a key process measure in micro ultrasonic machining (Micro-USM) as an efficient process for micromachining of hard and brittle materials. Process parameters such as ultrasonic vibration amplitude, static load, type of tool material, type and size of abrasive particles and slurry concentration can influence the surface quality. How...
