6.3 Program structure
G_code programs can always be freely programmed. The most important commands that
are included in the rule:
● Set a machining plane
● Call a tool (T and D)
● Call a work offset
● Technology values such as feedrate (F), speed and direction of rotation of the spindle (S
and M)
● Positions and calls, technology functions (cycles)
● End of program
For G code programs, before calling cycles, a tool must be selected and the required
technology values F, S programmed.
A blank can be specified for simulation.
