M88 Rotary tool spindle start (forward direction) M30 Memory mode operation reset & restart M09 Coolant stop (low/high pressure coolant) M08 Coolant start (high pressure coolant) Please note that those M-codes are not compatible to other builder’s machines and we customize them only for Nakamura machines. Let’s take a look at the often-used 22 M-codes with Nakamura machines.
There are about 80 M-codes designated from M00 to M99 fundamentally, but same as G-code, you do not need to use them all. In this way, the machine builders customise the commands for their own machines respectively. This was because even though the M-code digits were same, the commands in execution were different. Both machines adopted FANUC controllers so you tried the same M-code digits used for the old machine to the new machine to state the same commands, but you came across to failure. Imagine if you already had a machine produced by Builder A, then you purchased a new machine from Builder B. Therefore, the codes called for action vary from machine builder to builder. Since the purpose of M-code is to activate a machine, machine builders rules the programming codes rather than CNC controller manufactures. They are represented in numbers following sing M.įor example, M03 is a command for “Spindle start in forward direction”, and M08 is for “Coolant start”. M-code is miscellaneous function that we use in auxiliary command, calling for vary machine action. Here are the often-used 16 G-codes that you’d better remember. Only if you remember frequently used codes, you can write a program. The basic G-codes are about 70 in number from G00 to G99, but we do not usually use them all every time. Hence, these opposing codes are enclosed within one group to prevent from canceling commands each other.
Same as this condition, you cannot state “G02: Circular interpolation in clockwise” and “G03: Circular interpolation in counter clockwise” in a line because the machine cannot execute them simultaneously. This grouping is aimed to avoid from interfering each command.įor example, if you state “G00: Positioning”, you cannot write “G01: Cutting feed” in a same line because a machine cannot follow both commands at the same time. There is no need to be panic about the groups.

G-code has two types: one-shot codes (also called “non-modal”) that are valid only once, and modal codes that remain valid until another code in a same group is in execution. 2-1.G-codeĪs preparatory function, we mainly use G-code in manufacturing command, representing in numbers following sign G. Elementally, basic codes are present in two digits from 00 to 99, but depending on the configuration of a machine, we may use up to three digits. CNC programming is composed of languages called G-code and M-code.

Since Nakamura’s machines equip the FANUC controller, we explain about how to activate a program in an easy-to-understand manner using FANUC CNC programming codes as an example in this column.įirstly, you need to know about the language. Therefore, you need to be sure which CNC controller does a machine in use equip with before you start writing a program. All of the manufactures use G-code and M-code so you might misunderstand that the string of the written programs means same command and order, but actually the command could be different even though they use same codes. Programing codes are developed by several CNC controller manufactures such as FANUC, Siemens, Heidenhain and their systems are divided into lathe system and machining system. When we work on a material on the CNC machine, we use G-code and M-code for programming. 1.What is CNC programming?ĬNC stands for Computerized Numerical Control and a CNC machine is a machine computerized and numerically controlled. However, once you understand the rules, it is not so hard to understand. CNC programming sounds difficult like a killer phrase for non-skilled operators because of many codes and enigmatic rules.
