Total questions: 10
Worksheet time: 7mins
The following are the characteristic of a NON-CONVENTIONAL machining, EXCEPT.....
No tool wear
Low noise pollution
Comparatively low cost in machine set up
Require complex and skillful operations
The following are considered a non conventional machining process, EXCEPT...
Abrasive Water Jet Machining
Electrochemical Machining
Lathe Machining
Electro-discharge Machining
Why the Water-jet Machining is not suitable for very thick work piece?
It will cause Burr.
The work piece will over heat and melt.
The water jet have less consistent impact as the distance increases
The impact of the water jet on the work piece will cause deflection.
What is the function of an intensifier in the Water Jet system?
Store water
Control water flow
Increase the water pressure
Increase the kinetic energy of the water
In the ElectroChemical Machining process, there is the tool and work piece. Which is the Cathode in the configuration?
Tool
Work piece
Which of the following is the advantage of ElectroChemical Machining?
Able to produce any shape (including Sharp Corner).
Low investment cost
Corrosion Free
Low power consumption
How does an Electrical-Discharge Machining removes material from work piece?
By corrosion of chemical process
By electrical sparks
By melting it with laser beam
By spraying the material with water jet
In a Electrical-Discharge Machining, what is the width (with the "?") of the cut (shown in figure) called?
Kraft
Spark Gap
Kerf / Slot
Reel
Why doea the ND:YAG more suitable for metal than a CO2 Laser?
ND:YAG has higher wavelength
ND:YAG has lower wavelength
Which is the correct sequence to a Chemical Machining?
Clean material > Masking > Etching > Clean Mask
Clean Mask > Clean Material > Masking > Etching
Clean Mask > Masking > Etching > Clean Material
Masking > Etching > Clean Mask > Clean Material
