# State the function of G00, G94, M08 and M30 used in CNC part programming.

State the function of G00, G94, M08 and M30 used in CNC part programming.

## 1 Answer

### Answer :

1) G00 :- Rapid Traverse Function

G00 is the basic G-code for CNC programming to initiate rapid motion mode i.e used for quickly positioning the tool. G00 can be used where the tool is not directly in contact with work piece and where one wants to save the time.

2)G94 - Feed Rate Programming In “mm/min”

3)M08 – Coolant ON

4) M30 :-Program End with program reset OR

End of tape- Tape rewind Automatically

The most common way of ending a program is with an M30. The program will automatically reset to the beginning of the program which will give access to the operator to run the next cycle. Using M30 will help operator to save time during mass production. As soon as the program ends he can place the next component and start the next cycle.
