Ceramic ultrasonic machining.

The influence of different process parameters on the material removal rate for machining of magnesia stabilized zirconia is examined. The vibration frequency is 19 25 khz. Non thermal process creates no haz and little or no subsurface damage. During the operation the tool is pressed to the workpiece at a constant load.

Then a mechanistic approach to modeling the material removal rate during rotary ultrasonic drilling of ceramics is proposed and applied to predicting the material removal. Ultrasonic machining or strictly speaking the is a subtraction manufacturing process that removes material from the surface of a part through high frequency low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles. Ultrasonic machining is a low material removal rate mrr loose abrasive machining process in which the mirror image of a shaped tool can be created in hard brittle materials. Machining hard ceramics or soft optical materials has never been faster or easier.

Material removal is achieved by the direct and indirect hammering of abrasive particles against a workpiece by means of an ultrasonically vibrating tool. This is precise enough to be used in the creation of micro electro mechanical system components such as micro structured glass wafers. The amplitude of vibration 0 0005 0 002 13 50 μm. Advantages of ultrasonic machining.

An experimental study of the rotary ultrasonic drilling of ceramics is first presented. This method is the best choice for working with hard materials such as ceramic matrix composites ruby piezo ceramics glass ceramics quartz ferrite diamonds technical ceramics alumina pcd sapphire cvd silicon carbide and similar ones. Machining the precise mineral stones tungsten. Ultrasonic machine is useful for hard material.

Ultrasonic machining um of ceramics is the machining method using the action of a slurry containing abrasive particles flowing between the workpiece and a tool vibrating at an ultrasonic frequency. Ultrasonic machining offers many advantages over conventional laser machining of ceramic substrates. Diamond is cut for the desired shapes. As a result no post machining polishing or annealing processes are required to relieve residual stress and slag caused by laser.

The paper says about parametric optimization of ultrasonic. Machining the glasses ceramics. Piercing of dies and for parting off operation. Lower total cost higher yield.
