1. PROGRAMMING MACHINE NC/CNC (BASIC)
BASIC COMPETENCE : WRITING PROGRAMME MACHINE NC/CNC

2. LEARNING OUTCOMES After the sudent get the lesson are able to :
Knowing code programming CNC for machine frais certain
Understand the lesson write each code programming machine frais CNC
Writyes codes programming to paper program CNC with cirrectly and suitable with standard

3. CODE PROGRAMMING
Code of Pemrograman CNC consisted of the code of letter and number
Letter which is a lot of used is letter G, M, S, F, H, I, J, T N, K, D, X,Y, Z, and number 0 until 9

4. CODE PROGRAMMING Instruction code CNC Milling is: G00: moving position
Moving position is cutting move without shape
Programming format G00 is : N …. / G00 / X ….. / Z …

13. INTERPOLASI CIRCLE G02 AND G03
G02: Interpolasi contary of clockwise
G03: Interpolasi contrary of counter clockwise
Input format: N … / G02/ X± … / Z± … / F …
Inpu format : N … / G03/ X± … / Z± … / F …

15. BAGS MILLING SICLUS Siclus Pengefreisan kantong: G72
Used for the making of bag
Instruction format : N … / G72 / X ± … / Y± … / X± … / F …
Siclus movement is:

16. BAGS MILLING SICLUS

17. EXAMPLE PROGRAME G72

18. SICLUS DRIIL WITH PULLED G 83
G83: is order to drill with move to pulled throw total to deep drill
Movement 1: cutter step into the Z deepness 6 mm with the movement feeding (G01)
Movement 2: cutter return to starting points with the whisk ( G00)
Movement 3: cutter return to enter with the Z deepness increasing 6 mm.,
Movement 4: return to starting points
Instruction format: N … / G83 / Z± … / F …

19. SICLUS DRILLS WITH PULLED G 83

20. WRITING AND DECIDE ZERO POINT : G92
G92: instruction of record-keeping and dot stipulating of zero machine
at absolute pemrograman price
2. Programe format: N … / G92 / X ± … / Z± …
3. At programe G92, price X is show diameter

21. FUNCTION M
Code govern the letter M is code govern to equip and assist the code G.
Code M referred as by a ministrant comand
Code G referred as by a antecedent comand

22. Some code M and its meaning is which is a lot of used by
- Turn of rotation main axis
Repairing mistake program.
To continue the program depress knob “START”
M03
Rotation main axis clockwise
M05
Stop rotation of main axis
