Which G-code is used to set the feed rate in mm per minute in CNC programming?

• A) G95

• B) G94

• C) G97

• D) G96

What does the G95 code specify in CNC programming?

• A) Feed rate per minute

• B) Feed rate per revolution

• C) Constant surface speed

• D) Spindle speed control

What is the main purpose of using G97 in CNC programming?

• A) To set a constant surface speed

• B) To specify feed rate per minute

• C) To set a fixed spindle speed

• D) To enable feed per revolution

Which G-code cancels the constant surface speed mode (G96) and fixes the spindle speed to a specific value?

• A) G97

• B) G95

• C) G98

• D) G99

What is the purpose of G98 in CNC programming?

• A) Sets the feed rate in mm per minute

• B) Uses feed per revolution mode

• C) Returns to initial point in canned cycle

• D) Enables constant surface speed

In which situation would you use G99 instead of G98?

• A) When specifying feed per minute

• B) When controlling constant surface speed

• C) To return to the R-point in a canned cycle

• D) To set feed per revolution

What does G94 control in CNC programming?

• A) Constant surface speed

• B) Feed per minute

• C) Feed per revolution

• D) Fixed spindle speed

What is the main difference between G96 and G97?

• A) G96 sets feed rate per minute, G97 sets feed per revolution

• B) G96 uses constant surface speed, G97 fixes the spindle speed

• C) G96 controls canned cycles, G97 controls feed rate

• D) G96 is for rapid movement, G97 is for spindle control

Which G-code is typically used in drilling cycles to specify feed per revolution?

• A) G94

• B) G96

• C) G98

• D) G95

In which situation would you select G98 over G99 in a canned cycle?

• A) To maintain the feed rate in mm/min

• B) To use constant surface speed

• C) To return to the initial point after completing the cycle

• D) To enable feed per revolution
