Programming symbol
Every action of CNC machine running according to regulate program, every machine program be composed
of some
instruction segment
, and every instruction segment be composed of some
Function word
,
each function word must start by letter, parameter follow.
Definition of function word:
N --The No of instruction segment
G --Prepare function
M --Assistant function
S --Main axis function
L --Cycle times or delay time
X --X axis absolute coordinate value
Y --Y axis absolute coordinate value
U --The increment that X axis relative to current position
V --The increment that Y axis relative to current position
I --When cutting arc, the value that the coordinate of the circle centre subtract X axis start value
J --When cutting arc, the value that the coordinate of the circle centre subtract X axis start value
R --Specified arc radius
F-- Specified moving speed, used for G01,G02 and G03
Note 1: There are some appointments:
X[U]n -- It can be X or U, n express a value, but only appear once.
Y[V]n -- It can be Y or V, n express a value, but only appear once also.
PPn -- It can be assembled random axis, at least include one axis ,also can include two axis.
Note 2: The instruction execute order is sequence (except transfer and call sub program
instruction); In same
