CNC Memory, 4.6 GB (P12 & P77)

CNC Memory, 4.6 GB (P12 & P77)

A combination of Siemens options that, together, adds internal memory to the SINUMERIK ONE to bring in and integrate large files (such as CAD and CAM).

DXF Reader (P56)

DXF Reader (P56)

Open DXF files on the SINUMERIK ONE to easily transfer data into your program. Program faster and reduce errors on programming dimensions. Open and use elements of multiple DXF files in the same program. Works within all the programming methods. Easily command specific features from drawing elements. Set your own part reference independent of the drawing origin.

Handwheel Run (M08)

Handwheel Run (M08)

Run the programmed moves by turning the handwheel. You control the feedrate by moving the Manual Pulse Generator on the control panel and the actual programmed path is moved. Adjust the relationship between the handwheel turns and the feedrate with 4 different resolution settings. Seamlessly go between Handwheel Run and fully automatic CNC run. Great for setups and for confidence making that first part!

Execution from External Storage (P75)

Execution from External Storage (P75)

Enables the use of an external memory device for running and editing programs. Allows your memory device to function like an expansion of your internal SINUMERIK ONE memory, without any restrictions on programs, subprograms, commands or even transferring to another machine.

ShopTurn (P17)

ShopTurn (P17)

True conversational programming you can do right on the shop floor. Write complete part programs or insert a feature within another program. With guidance from Animated Elements, Tool Tips, Dynamic Graphics, Canned Cycles and Context-Sensitive Help to guide you can create programs with ease. You won’t have to go back to the person who programmed the part to fix or add to your program.

Residual Material Detection (P13)

Residual Material Detection (P13)

The SINUMERIK ONE automatically recognizes Rest Machining situations. Simply call up the Residual Machining canned cycle, enter a few simple inputs and the control does the rest.

Match the tool to the operation for fastest machining: large tool for hogging, smaller tool for regions the large tool won’t reach. Multiple Residual Machining cycles in the same feature gives you the flexibility to minimize cycle times.

Access MyMachine OPC UA (P67)

Access MyMachine OPC UA (P67)

The OPC UA (Unified Architecture) standard is particularly suitable for data exchange across different levels as it is independent from specific operating systems, has secure transfer procedures and better semantic description of the data.

OPC UA not only makes data available, but also provides information about the data (e.g. data types). This enables machine-interpretable access to the data.
