The programmable functions of CNC machine tools are divided into two categories: one is used to control the tool trajectory, that is to say the movement of each food axis, such as interpolation linear / arc, food control The adjustment of the unit of size of this type of function is called the preparation function, composed of letter G and two figures, also known by the code name G. Another type of Function is called auxiliary functions, which are used to complete the program execution control, control of the pin, tool control, control of auxiliary equipment and other functions. Among these auxiliary functions, the TX X is used for the selection of tools and SX XXX is used to control the speed of the pin. Other functions are implemented by M Code composed of letter M and two figures.

3. Currently used arithmetic
Addition: # i = # J + # K
Subtraction: # i = # j- # k
Multiplication: # i = # j * # k
Division: # I = # J / # K
Sinus: # i = sin[#j]
Anti-Sine: # I = Asin[#j]
Cosinus: # i = cos[#j]
Reverse cosine: # i = acos[#j]
Tangent: # i = tan[#j]
Arctangent: # I = Atan[#j]
Root square: # i = sqrt[#j]
Absolute value: # I = ABS[#j]
Rounded: # i = round[#j]
Rounded: # i = fix[#j]
Arrondissement: # I = FUP[#j]
Natural logarithm: # i = ln[#j]
Exponential function: # i = exp[#j]
或 ： # i ＝ # Jor # K
Xor: # i = # jxor # k
与 ： # i ＝ # and # k
Convert from BCD to BAC: # I = BAC[#j]
Convert BAC to BCD: # I = BCD[#j]
4. Logical operators
EQ: equal to
Ne: not equal to
GT: More than
GE: greater than or equal to
LT: Small
The: less than or equal to
5. Transfer and program loop
Unconditional transfer: Goto
Conditional transfer: if [条件表达式]
IF [条件表达式] Goto n, if the condition is satisfied, go to the program of program n
IF [条件表达式] So, like: if [#I=#J] Then # k = 0
6.
WHILE [条件表达式] DOM (M = 1.2 ,, 3)
…
END
If the condition is satisfied, the program between Dom and Endm will be executed (until the condition is not satisfied), otherwise the program after Endm will be in the place.
