30 3 Positioning with Manual Data Input (MDI)
3.1 Programming and Executing Simple Machining Operations
3.1 Programming and Executing
Simple Machining Operations
The Positioning with Manual Data Input mode of operation is
particularly convenient for simple machining operations or pre-
positioning of the tool. It enables you to write a short program in
HEIDENHAIN conversational programming or in ISO format, and
execute it immediately. You can also call TNC cycles. The program is
stored in the file $MDI. In the operating mode Positioning with MDI,
the additional status displays can also be activated.
Positioning with manual data input (MDI)
Select the Positioning with MDI mode of operation.
Program the file $MDI as you wish.
To start program run, press the machine START
button.
Example 1
A hole with a depth of 20 mm is to be drilled into a single workpiece.
After clamping and aligning the workpiece and setting the datum, you
can program and execute the drilling operation in a few lines.
First you pre-position the tool in L blocks (straight-line blocks) to the
hole center coordinates at a setup clearance of 5 mm above the
workpiece surface. Then drill the hole with Cycle 1 PECKING.
Limitation
FK free contour programming, programming graphics and
program run graphics cannot be used. The $MDI file must
not contain a program call (PGM CALL).
