3. Preparatory "G" functions
They determine the geometry and work conditions such as linear
and circular interpolations, chamfers, canned cycles, etc.
The section on "1.3.1 List of preparatory "G" functions" in this
chapter shows the available G functions.
4. Point coordinates "X, Y, Z..."
They determine the movement of the axes.
The axis name is defined by 1 or 2 characters. The first character
must be one of the letters X - Y - Z - U - V - W - A - B - C. The second
character is optional and will be a numerical suffix between 1 and
9. This way, the name of the axes may be any in the "X, X1...X9,...C,
C1...C9" range.
The movements are represented by the axis letter followed by the
target position for the axis.
X100 Y34.54 X2 = 123,4 A5=78.532
Depending on the units, the programming format will be:
• In millimeters, format ±5.4 (5 integers and 4 decimals).
• In inches, format ±4.5 (4 integers and 5 decimals).
5. Technological functions "F" and "S"
They determine the feedrate of the axes and the spindle speed.
The feedrate is represented by the letter "F" followed by the desired
feedrate value.
6. The spindle speed is represented by the letter "S" followed by the
desired speed value.
7. Tool number "T" and tool offset "D"
It selects the tool and tool offset to be used to carry out the
programmed machining operation. The tool is represented by the
letter "T" followed by the tool number (0-4294967295). The tool
offset is represented by the letter "D" followed by the tool offset
number.
8. Auxiliary functions "M" and "H"
With the auxiliary functions, it is possible to control machine
elements such as spindle turning direction, coolant, etc.
They are represented by the letters "M" or "H" followed by the
function number (0-65535)
9. Number of block repetitions "NR"
It indicates the number of times the block will be executed.
It can only be programmed in blocks containing a movement.
If the block is under the influence of a modal canned cycle, the latter
will be repeated as many times as the block repetition has been
programmed. When programming NR0, the movements will be
executed, but the modal canned cycle is not executed at the end
of each one.
