Experimental investigation of the cutting forces and edge

2018/10/3Ultrasonic-assisted drilling (UAD) is a promising technology used for machining difficult-to-cut materials. In this paper, experimental investigations were conducted to study the drilling forces and edge chipping for soda glass using diamond abrasive tools. Cutting fluid was used at different levels of feed rate, spindle speed, and tool concentrations. The thrust force, torque, and edge

2016/2/1Edge chipping induced by rotary ultrasonic drilling (RUD) restricts the applications of brittle materials. It should be possible to reduce or eliminate edge chipping by optimizing the process parameters based on efficient theoretical modeling of the size of the edge chip.

Combination of Ultrasonic Vibration and Cryogenic

The main objective of this study is to develop a thermo-elastic-plastic coupling model, based on a combination skill of ultrasonically assisted cutting and cryogenic cooling, under large deformation for Inconel 718 alloy machining process. The improvement extent on cutting performance and tool life promotion may be examined from this investigation. The critical value of the strain energy

40Khz Ultrasonic Cutting And Sealing Equipment for

Therefore, the ultrasonic cutting does not require a sharp cutting edge, nor does it require a large pressure, and does not cause any chipping or breakage. At the same time, since the cutting blade is subjected to ultrasonic vibration, the frictional resistance is particularly small, and the material to be cut is not easily adhered to the blade.

Micromachines

The mode of crack propagation was continuous cracks in conventional sawing process, while the expansion mode in ultrasonic assisted sawing was blasting microcracks. This results in the cutting force of ultrasonic assisted sawing becomes much smaller than that of conventional sawing process, which can reduce the size of edge chipping and improve the quality of machined surface.
