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
