G-code, M-code Programing CNC (1)

Dalam programing mesin CNC ( Computer Numerically Controlled ) kita mengenal G-code, M-code, dan T-code. Berikut ini sedikit ulasan tentang G-code dan M-code pada mesin cnc.

Kode G :menyatakan gerakan
Kode M :menyatakan fungsi mesin



G-CODE
jenis-jenis G-code di kelompokan menjadi 2 kelompok.

1.jenis basic/dasar meliputi:

-G00: gerakan cepat tanpa pemakanan benda kerja -->bergerak lurus
-G01: gerakan memotong/pemakanan benda kerja -->bergerak lurus
-G02: gerakan memotong melingkar searah jarum jam
-G03: gerakan memotong melingkar berlawanan arah jarum jam

2. jenis lanjut/siklus meliputi:

-gabungan langkah G00 dan G01 yang disedehanakan
-G90: sistem kordinat absolut
-G91: sistem kordinat incrimental

Berikut ini daftar G-code:

M-CODE
Seperti halnya G-code, M-code juga memiliki 2 kelompok, dasar dan lanjutan:

M-code Dasar meliputi:
M02 - menghidupkan poros mesin (spindel on) berputar searah jarum jam (CW).
M03 - menghidupkan poros mesin (spindel on) berputar berlawanan arah jarum jam (CCW).
M05 - mematikan poros mesin (spindel off)
M30 - langkah terakhir (program end)

M-code Lanjutan meliputi:
M08 : Menghidupkan pendingin/coolant
M09 : Mematikan pendingin/coolant
Dll.

Berikut ini daftar M-code:

Untuk cnc Mill:

M00 - Program Stop
M01 - Optional Stop
M02 - Program End
M03 - Spindle Clockwise
M04 - Spindle Counter Clockwise
M05 - Spindle Stop

Karena M-code merupakan code untuk fungsi mesin maka ada beberapa perbedaan M-code pada beberapa jenis mesin sesuai maker mesin.

Sekian..jika ada kekurangan mohon di koreksi... ditunggu komentarnya.
Terima kasih.
