Kerf
Specifies the amount of kerf that will be applied to the current part program. Care should
be taken when selecting a kerf value as this parameter can cause invalid geometries to be
generated. For example, adding a kerf of 0.5” to an arc with a radius of 0.25”. After
entering a kerf value, the kerf compensated cut path can be viewed by pressing the Kerf
soft key under the Part Options menu.
Kerf Variable / Kerf Value
Creates a kerf variable table that assigns a variable to a Kerf value. Up to 200 variables
can be entered to create a reference table.
This kerf variable can be used within a part program to define the kerf value and as torch
parts wear, the kerf value changes. If the kerf variable value is updated as the
consumable wears and changes, the new value will be called by the kerf variable
command with all programs loaded that use the variable.
The EIA-274D part code for left kerf variable is the G43 code.
Example:
G43 D1 X0.06
Kerf Variable Setting
Kerf Variable
A number from 1-200 can be used
Kerf Data
The selected kerf value
Trial/Cut Speed
Specifies the speed for the current cut mode. These speeds are saved independently for
trialing and cutting. Both speeds are limited to the maximum machine speed. Cut and
trial speeds can be executed at the embedded F-code speed within a part program.
Marker 1 / Marker 2 Speed
Specifies the speed for the selected marker. These speeds are saved independently for
each marker and are executed through the marker tool selection within a part program.
Marker 1 is activated by EIA RS-274D M09 and M10, or an ESSI 9 and 10. Marker 2 is
activated by EIA RS-274D M013 and M14, or an ESSI 13 and 14.
Plate Size
Specifies the dimensions of the current plate. This dimension is used when loading a part
to determine if it will fit on the plate. It is also used for viewing the part in screen view.
Vent Controls 1 - 50
Enter values for up to fifty programmable zones for fume extraction damper control.
Based on the machine position, the vent control outputs to activate dampers at the
selected zone for increased performance.
