Blank form update (FUNCTION TURNDATA)

During turning operations workpieces must often be machined

with several tools. Often a contour element cannot be completely

finished because the tool form does not permit this (e.g. with

a back cut). In this case, single sub-areas have to be reworked

with other tools. The TNC detects the already machined areas

with the blank form update and adapts all approach and departure

paths to the specific, current machining situation. With the shorter

machining paths, traverses in the air are avoided to significantly

reduce machining time.

To activate the blank form update, program the TURNDATA BLANK

function and link to a program or subprogram with a workpiece

blank specification. The workpiece blank defined in TURNDATA

BLANK determines the area to be machined with the blank form

update. TURNDATA BLANK OFF deactivates blank form update.

The TNC optimizes machining areas and approach

motions with blank form update. The TNC takes into

account the specific tracked workpiece blank for

approach and departure paths. If parts of the finished

part extend beyond the workpiece blank, this may

damage the workpiece and tool.

Blank form update is only possible with cycle

machining in turning mode (FUNCTIONMODETURN).

You must define a closed contour as the workpiece

blank for the blank form update (start position = end

position). The workpiece blank corresponds to the

cross-section of a rotationally symmetrical body.
