Which of the following processes would be appropriate for cu

Which of the following processes would be appropriate for cutting a narrow slot, less than 0.4mm wide, in a 10mm thick sheet of fibre-reinforced plastic?

(a) electrical discharge machining and wire electrical discharge machining

(b) electrical discharge machining and oxyfuel cutting

(c) abrasive jet machining and chemical milling

(d) laser beam machining and water jet cutting

please provide a brief explanation

(I think laser beam machining and water jet machining should be the answer. They are usually chosen as cutting processes for non-metals like plastics.)

Solution

Laser beam machining and water jet cutting are used because in order to cut 0.4mm slot it is possible with laser only
