HUST CNC H6D-T Manual
2 - 34
1. Function Command: The G-code, for example, is used to instruct the machine to
perform actions, such as linear cutting, arc cutting, or thread cutting.
2. Positioning Command: X, Z, U, W commands, for example, instructs the G-code
of the machine to stop at a specified position; i.e. destination or end point of the
action.
3. Feed Rate Command: This command instructs the tool to cut (G-code) at a
specified speed.
4. Auxiliary Function: The M, S, T, L commands, for example, determine the start,
stop, spindle speed, tool selection, and execution times of the machine.
However, not every block contains these four commands. Some blocks have only one
command. This will be further discussed in Chapter III.
Except for the block serial number of the block N___, all other components of the basic
block format are commands. A command contains a command code (letter), a +/- sign,
and some numbers.
Basic Command Format (e.g. the positioning command):
X-10.000
X : Command code
"-" : +/- sign (+ can be omitted)
10.000 : Destination of a tool positioning action.
The command codes include the function command code, positioning (or coordinate)
command code, feed-rate command code, and auxiliary function command code. Each
command code has its own definition and the machine behaves according to the command
code given. The command codes of H6D-T Series and their definitions are described
below.
F: Feed-per-rotation command. mm/rev or mm/min
G: Function code
I: The X-axis component of the arc radius.
K: The Z-axis component of the arc radius.
L: Repetition counters.
M: Machine control code.
N: Program serial number.
P: Call subprogram code; parameter in canned cycles; tool number for tool
compensation.
Q: Parameter in canned cycles.
