What is G-code used for in CNC programming?
G-code controls the movements and operations of a CNC machine, such as positioning, cutting, and drilling.
What does the M-code typically control in a CNC program?
M-codes are used to control machine functions such as turning the spindle on or off or coolant control.
What is the purpose of zero return in CNC machines?
Zero return sets the machine to a reference point, ensuring accurate positioning and tool changes.
What does the term 'feed rate' refer to?
Feed rate is the speed at which the cutting tool moves through the material, affecting quality and efficiency.
What is the purpose of tool offset in CNC machining?
Tool offsets adjust for tool length and diameter, ensuring precise cutting and drilling.
Which CNC command is used to return the machine to its home position?
The G28 command is used to send the machine back to its home or origin position.

What is spindle speed measured in?
Spindle speed is measured in revolutions per minute (RPM), indicating how fast the tool rotates.
What is the function of coolant in CNC machining?
Coolant reduces heat and friction, prolonging tool life and improving surface finish.
Why is simulation important before actual machining?
Simulating a CNC program helps detect errors and prevents damage to the machine or workpiece.
