Machining Subminiature Features on Fibre Optics: The Dicing Process

The video tutorial demonstrates the process of machining 200 Micron wide grooves in flat optical fiber using a dicing machine. It covers sample preparation with UV-sensitive adhesive tape, setting up and adjusting the dicing machine, programming parameters, and aligning the workpiece. The machining process is executed with precision, and the final product is inspected using an optical microscope.

What is the purpose of using UV-sensitive adhesive tape in the machining process?

• To allow easy removal of the part after machining

• To enhance the precision of the cut

• To provide a strong bond during machining

• To protect the optical fiber from damage

What material is the flat optical fiber made from?

• Plastic

• Silica

• Glass

• Metal

Why is a diamond blade used in the dicing machine?

• It is cheaper than other blades

• It provides a smoother finish

• It can cut through hard materials like silica

• It is easier to replace

What is the purpose of the shroud fitted around the blade?

• To reduce noise during operation

• To ensure safety in case of blade failure

• To protect the blade from dust

• To enhance cutting speed

What is the role of the height sensing spacer in the machining process?

• To adjust the blade speed

• To calibrate the blade height relative to the table

• To measure the thickness of the workpiece

• To align the workpiece with the blade

Why is the blade dressing process important before cutting?

• To clean the blade

• To test the machine's functionality

• To ensure the blade is sharp

• To prepare the blade for precise cutting

How is the alignment of the workpiece with the blade achieved?

• By manual adjustment

• Using a laser guide

• Using a ruler

• With an inbuilt microscope
