Question

Advantages and disadvantages of ultrasonic machining process

Answer 1

Advantages:
1) This type of process produce less heat.
2) You can do the machining of hard as well as brittle material in it.
3) It can be used for non-circular holes drilling just like in glass.
4) This may be use for hard materials threading.

Disadvantage:
1) The requirement of skilled labor for this machining process take it to a disadvantage
2) Regular repairing work is needed here.

3) This process result in increased tool wearing.

Answer 2

Advantages of ultrasonic machining include:

The process is non-chemical, non-thermal and non-electrical, leaving the physical and chemical properties of the work piece unchanged. This low-stress process translates into high reliability for your critical applications.

 

Multiple features can be machined at the wafer or substrate level simultaneously, and the process is scalable. The process is often the highest quality and lowest cost solution.

 

Ultrasonic machined features have vertical side walls, that can preserve valuable space for designs that results in higher productivity.

 

The process integrates well with semiconductor and MEMS processes. It can be aligned to previously patterned, machined, or etched substrates.

 

Disadvantages:

It is slower when compared to other mechanical process.

 

Tool wear is high because abrasive particle affect both work-piece and tool.

 

  It can machine only hard material. Ductile metal cannot be machined by this method.

  

 It cannot used to drill deep hole.
