AWJM

Applications and Products

Applications

• Industries: automotive, aerospace, electronics
• Materials: aluminum, titanium, heat resistant alloys, granite
  Products
• Engine components for aircrafts
• Titanium body parts for aircrafts
• Aluminum body parts for automobiles

Advantages and Disadvantages

• Similar to WJM Advantages and Disadvantages
• It is like Advanced Manufacturing/Lectures/Lecture 5/AJM + Advanced Manufacturing/Lectures/Lecture 5/WJM

Advantages

• Best of both processes: can cut both hard and soft materials or in very thick sections
  • Low kerf even with 200mm-thick materials
• Low cutting forces on WP
• Localized structural changes
• No slag/cutting losses
• Limited tooling requirements
• Finish 125-250 microns

Disadvantages

• High noise levels
• Cannot cut materials sensitive to moisture (degrade quickly)
• Kerf width (1.5-2.3mm) varies with material thickness
  - Hard materials -> widest kerf at the top
  - Soft materials -> widest kerf at the bottom
  • Taper on cut edge is a function of material hardness

Working Principle

• Advanced Manufacturing/Lectures/Lecture 5/AJM + Advanced Manufacturing/Lectures/Lecture 5/WJM
• Just like Advanced Manufacturing/Lectures/Lecture 5/WJM, however abrasives are mixed with the water jet
• Specialist for hard materials
