This function is used to mill the outside contours on turned parts,
e.g. four--sided parts (linear axis with rotary axis).
3D interpolation with two linear axes and one rotary axis is also
possible.
The benefits afforded by Transmit are simplified programming and
improved machine efficiency through complete machining: Turning
and milling on the same machine without reclamping.
This function allows axes (tailstocks, sleeves) to be traversed to a
fixed stop position in order, for example, to clamp workpieces. The
contact pressure can be defined in the part program.
The maximum permissible travel range for linear axes is ± 9
decades. The absolute value depends on the selected input and
position control resolution and the unit of measurement (inch or
metric).
Users can define variables in the --> part program or data block
(global user data) for their own use. A definition contains a data type
specification and the variable name. See also --> system variable.
All programs and data such as part programs, subroutines,
comments, tool offsets, zero offsets/frames and channel and
program user data can be stored in the common CNC user memory.
--> Part program
A variable is defined through the specification of a data type and a
variable name. The variable name can be used to address the value
of the variable.
In order to achieve an acceptable travel velocity in movements
which call for very small adjustments of position in a block, the
control can --> look ahead.
Words with a specific notation which have a defined meaning in the
programming language for --> part programs.
