Operational modes

Manually controlled operation
The manually controlled operation is possible in the "JOG" and "MDA" operating modes. Refer
to chapter "Manual mode" of the operating instructions of "SINUMERIK 808D".
In JOG mode, you can perform the following machining operations:
Measuring tools

Measuring the workpiece

Setting parameters for face machining of a workpiece blank

Setting the spindle speed and direction, activating other M function and changing the tool,

Setting the axis positions in the relative coordinate system.

In MDA mode, you can create programs, load existing programs from directories in the "Pro-
gram Manager" into the MDA buffer, or execute the current program.
Automatic mode
Refer to chapter "Setup machine" of the operating instructions for "SINUMERIK 808D".

Programming

For further working steps please proceed as described in the operating instructions "Part pro-
gramming, system, programming and cycles" for SINUMERIK 808D.
Manual resp. part programming:
For this kind of programming, the programs must be created manually and entered in the con-
trol unit. The direct programming in the DIN-Code is a complex method which requires lots of
skills. Nowadays this task is mostly taken over by CAD/CAM systems which directly create an
operating program using a graphical user interface.
Automatic programming:
Construction data are transmitted (semi-) automatically to an executable program by means of
the CAD/CAM program (for instance a 3D-CAD program including downstream co-processor).
For this kind of programming, a 3D model is designed using a PC. The motion-sequence of the
machine is calculated by means of an operating sequence which is predefined by the user.
These programs access the tool data base which includes all tool parameters (speed, feed,
diameter, etc.). Due to this systematic program structure, the user is able to create a complete
program in a short period of time without having any knowledge of the individual program com-
mands and their syntax.
