How To Make CNC VMC Programme

How To Make CNC/VMC Programme with step by step - 



Firstly divides the cnc/vmc programme in three parts -

1. Header

2.Operational part

3. Footer

1. Header -


In this part mostly G and M code are used same for maximum cnc/ vmc programme
It consist following code in most of cnc/vmc  programming

G00 - Rapid motion

G17,18,19 - For plane selection

G40,41,42 - For tool compensation (off, left on, right on)

G70,71 - For dimension  (inch, mm)

G90,91 - For co-ordinate system (absolute, incremental)

G94,95 - Feed rate (mm/min,mm/rpm)


M08 - coolant on

M03,04 - Spindle rotation direction (cw, anti cw)

T - Tool selection

D1 - Its used in siemens only

S - Speed of machine

F - Feed rate


2. Operational Part -


it consists blue print of machine working path. This is main part because it decide how to machine will cut the required job. It contains co-ordinate for tool path with the help of drawing.

3. Footer -


After comlete the job, In this part mostly machine stopping codes are written. it contains following codes most of time -

M05 - Spindle stop

M09 - Coolant off

G75 - Home position  (for siemens)

M02/M30 - End of Programme
