General

HMI sl is an operating and programming software for turning machines that makes it easy for
you to operate a machine and to program workpieces.
The programming of the workpiece is graphically supported (help graphics).
The parameter area in the entry field for the cycle program creation is divided into three main
columns below the screen name:
● Parameter identifiers
● Entry field: Number or text input with up to 11 digits (incl. sign and decimal point)
● Unit: Units, absolute (abs), incremental (inc), ...
4.3.2

Current planes in cycles and input screens

Each input screen has a selection box for the planes, if the planes have not been specified
by NC machine data.
● Empty (for compatibility reasons to screen forms without plane)
● G17 (XY)
● G18 (ZX)
● G19 (YZ)
There are parameters in the cycle screens that have names dependent on this plane setting
and that are displayed accordingly, e.g. Z0, Z1 or X0, Y0.
If the entry field remains empty, the parameters, the help screens and the broken-line
graphics are displayed in the default plane (can be set via machine data):
● Turning: G18 (ZX)
● Milling: G17 (XY)
The plane is transferred to the cycles as new parameter. The plane is output in the cycle, i.e.
the cycle runs in the entered plane. It is also possible to leave the plane fields empty and
thus create a plane-independent program.
The entered plane only applies for this cycle (not modal)! At the end of the cycle, the plane
from the main program applies again. In this way, a new cycle can be inserted in a program
without having to change the plane for the remaining program.
