Micro-ultrasonic machining (MUSM) is an effective way of processing microstructures made from hard and brittle materials, although controlling the fluctuation of the machining force during processing is difficult. To control the quality of micro-holes fabricated in hard and brittle materials, MUSM with force control (MUSMFC) is used to study the edge chipping rate (ECR) and material removal rate (MRR)...
The principle of rotary ultrasonic machining and the design of the multi-function CNC ultrasonic machine tools are introduced in this paper. Four kinds of experimental researches such as abrasive shock processing, ultrasonic drilling, ultrasonic milling and ultrasonic carving could been performed on the self-developed machine tools. A contrast experiment between ultrasonic drilling and non-ultrasonic...
