Fundamentals; Machining Planes - Siemens SINUMERIK 840D sl Operating Manual

Program blocks
You determine the individual machining steps in the program blocks. In doing this, you specify
the technology data and positions, among other things.
Linked blocks
For the "Contour turning", "Contour milling", "Milling", and "Drilling" functions, program the
technology blocks and contours or positioning blocks separately. These program blocks are
automatically linked by the control and connected by brackets in the process plan.
In the technology blocks, specify how and in what form the machining should take place, e.g.
centering first, and then drilling. In the positioning blocks, determine the positions for the drilling
or milling machining, e.g. position the drill-holes in a full circle on the face surface.
End of program
End of program signals to the machine that the machining of the workpiece has ended. Further,
here you set whether program execute should be repeated.
Note
Number of workpieces
You can enter the number of required workpieces using the "Times, counters" window.

Machining planes

A workpiece can be machined on different planes. Two coordinate axes define a machining
plane. On lathes with X, Z, and C axes, three planes are available:
● Turning
● Face
● Peripheral surface
Machining planes, face and peripheral surface
The face and peripheral machining planes require the CNC-ISO functions "Face surface
machining" (Transmit) and "Cylindrical peripheral transformation" (Tracyl) to be set up.
These functions are a software option.
