840D/FM-NC:
– Operating area of the control unit
– Computation parameter, can set or scanned in the program
at the discretion of the programmer for any purposes
he may deem meaningful.
A sequence of instructions to the NC control which combine to
produce a specific -> workpiece by performing certain machining
operation on a given -> blank .
The part program management function can be organized according
to -> workpieces. The number of programs and data to be managed
determine the size of the user memory. Each file (programs and data)
can be given a name consisting of a maximum of 24 alphanumeric
characters.
Programmer
Programmable logic control: -> Programmable logic control.
Component of the -> NC control: A control which can be programmed
to control the logic on a machine tool.
A coordinate system which defines the position of a point on a plane in
terms of its distance from the origin and the angle formed by the
radius vector with a defined axis.
Control is switched off and then switched on again.
It is necessary to perform Power On after loading the cycles.
Operating area of the control.
Sequence of instructions to the control.
Calculation parameter. The programmer of the -> part program can
assign or request the values of the R parameter as required.
The highest traversing speed of an axis. It is used to move the tool
from rest to the -> workpiece contour or retract the tool from the
contour.
