The Sinumerik Operate 840D SL is part of the changeable control WinNC. WinNC allows the user to learn all CNC industry controls that are common on the market, on a single machine. One of these controls is the Sinumerik Operate 840D SL.

It corresponds in handling and function the particular original control and it can be used on a commercial PC. The user has the possibility to work on the PC as well as on the machine control and gets familiar with all aspects of control programming in detail.



Data in/output of workpiece program files:
Workpiece program files can include several main and subprograms and further corresponding tool data. Moreover, workpiece data, R-parameter and zero offsets can be exported and imported.

Contour processor with graphic simulation:
The contours the workpieces should have after the machining process are illustrated by graphics in the programming process.

In order to ease the operation and the programming the control is equipped with an editor with helping cycles and pictures.

Preliminary block run:
Already finalized NC codes can be skipped.

Intermediate memory storage:
Data that are stored in the intermediate memory storage can be renewed in the programming process.

Setting Data:
JOG feed and speed limitations can be entered.

Dry run:
In the run-up to the machining process collisions and programming mistakes can be avoided and corrected by using the dry run.

Automatic measuring of position offsets:
When scratching the measured workpiece the position offsets will be taken over.

Automatic measuring of tools:
When scratching the reference workpiece the workpieces offsets will be taken over.

Alarms, signals, versions and customer information are displayed by the diagnostics.
