What is the main personal safety step (PPE) mentioned and worn by the instructor at the beginning of the video?
Leather gloves
Safety boots
Face mask
Apron
What is the shape of the electrode used in this video project?
Round shape
Square shape
Inverted 'G' shape
Inverted 'A' shape
Where is the workpiece placed and secured during this process?
Regular vise
3-jaw chuck
Held by hand
Magnetic table
Why is it important to clean the electrode holder before attaching it to the machine?
To make it shiny
To ensure the electrode sits flat and aligned
To prevent rust
To allow faster electric current
What is the purpose of the 'Alignment' process (referred to as 'element' in the video) performed using a dial indicator?
To ensure the electrode is vertical and aligned with the machine axis
To sharpen the tip of the electrode
To weigh the electrode
To heat the electrode before use
When setting the height (Z-axis), what should be done when the electrode touches the surface of the workpiece?
Immediately start cutting
Shut down the machine immediately
Set the Z value to 0 (Zero setting)
Lift the electrode as high as possible without recording data
What is the function of the 'Home Center' or 'Hole Center' shown in the video?
To drill holes
To find the center point of the workpiece
To cool the machine
To reset the machine to factory settings
How many main axes need to be set before starting the program?
Only 1 axis
Only 2 axes
3 axes (X, Y, and Z)
No axes need to be set
What is the technical term for the raw metal material that will be cut?
Master mold
Scrap
Workpiece
Tool
Why must the electrode be tightly secured to the holder?
To prevent movement that affects dimensional accuracy
To ensure the electric current is cut off
To prevent the machine from making noise
To save electrical energy
What type of liquid is used in the EDM Die Sinker machine tank?
Regular tap water
Cooking oil
Nitrogen gas
Dielectric fluid
What happens when the 'Magnet ON' button is pressed?
The electrode starts to rotate
The workpiece is locked tightly on the machine table
The machine starts cutting automatically
The machine light goes off
Based on the video, in which direction is the electrode moved to perform the main cutting?
Downward (Negative Z axis)
Only to the left
Upward
Rotating 360 degrees
What information needs to be entered in the 'Edit Code' display or programming?
Full name of the operator
Today's date only
Cutting parameters and coordinates
Electrode color
Why is the dimension size of the block (e.g., 52mm) considered when finding the center?
To determine the material price
To calculate the midpoint by dividing the size by two
To choose the size of the vise
Just for fun
What happens to the work result if the electrode is not aligned properly?
The machine will explode
The shape on the workpiece will be skewed/inaccurate
The electrode will become harder
There will be no effect
The electrode material in the video appears reddish. What is most likely the material?
Aluminum
Plastic
Wood
Copper
What is the main requirement for a workpiece to be processed using the EDM machine?
It must be very soft
It must be made of glass
It must conduct electricity
It must be black
What is meant by 'Z-depth' in machine settings?
How deep the electrode needs to cut into the workpiece
Machine speed
Amount of fluid in the tank
Weight of the workpiece
After the 'Run' button is pressed, what should the operator do?
Go home immediately
Ensure the process runs smoothly and monitor the initial cutting condition
Turn off the main switch
Remove the workpiece immediately
