Probe System - Part Only

Probe System - Part Only

The Renishaw OMP40-2 3D touch-trigger inspection probe is a compact touch probing solution that can be used out-of-the box with the native probing cycles of the SINUMERIK ONE CNC. Using a kinematic mechanism, the OMP40-2 probe is able to achieve a repeatability of 1µm. Optical transmission sends the data to the control without the use of cables. Includes the OMI-2T Optical Receiver.

This option is highly recommended to replace manual edge finders to decrease the amount of time in set-up. The probe may also be integrated into Auto cycles to decrease errors, downtime and scrap.

Tool Setups

Setting tools is simple due to the icons and Animated Elements that guide your selections. You define number of flutes, tip angle, cutting edges, holder angle, tool type and even tool life. A Magazine view shows which tools are in the magazine.

Tool, Spindle, M-Code (TSM)

A single key give you access to features such as loading tools, activating a work coordinate or turning on a spindle. All operations are commanded by answering conversational prompts, without any G-codes.

Return from Jog (REPOS)

while running programs, the SINUMERIK ONE can halt the current operation and the tool tip can be jogged away from the part surface, allowing you to inspect the tool or part. the REPOS feature let’s you return to the part where the machining was stopped.

Mid-program Start

Stuff happens, power outages, tool breakage, unanticipated moves. The SINUMERIK ONE gives you unprecedented ability to get back to where you were in the part with a high degree of confidence and with minimal work. Powerful Block search and Interrupt point combine to get you started exactly where you left off or at a point before…just to make sure. This powerful routine even enables a tool retract/recover that is able to define the proper place and speed to recover a tap stranded by an unplanned interruption.

Control Options

Note: (O) = optional

APO — Auto Power Off (O)

Will command the SINUMERIK ONE to shut down power at the end of a program run. This option is great for untended machining so the machine will shut down after the last part is run. Simply press the APO button on the control panel after the run is initiated.

3D Simulation (P25) (O)

3D Solid digital twin of your part, faithful in every programmed detail. You can check your program by close inspection of each detail using the touchscreen operation of the 19” screen of the SINUMERIK ONE on the VMCsi.

Advanced Surface Motion Control (S07) & Top Surface - Cycle 832 (S17) (O)

Advanced Surface and Top Surface are both advanced algorithms that analyze look ahead and velocity. The software analyses the program and converts points to splines to create a superior toolpath that is processed smoothly through the SINUMERIK ONE run engine.

You are able to choose the between maximizing Machining Velocity, Surface Quality and Dimensional Accuracy. For example, turning on the “Smoothing” function (in Top Surface) will greatly increase part surface quality but may possibly slow the machining. This advanced software puts the trade-offs into your hands – where it belongs.

  • Advanced Surface — Best for high-speed roughing applications, but also great for achieving optimal results for general milling. Highly recommended, and part of the One Dynamics Options Package for Job Shops.
  • Top Surface — The newer of the algorithms, this advanced software will actually fix problems with the imported CAM data, detecting gaps in the points distribution that will result in jerking or hesitations as the program runs. This option is best for high-speed finishing in mold making where the very best surface quality is required. Part of the One Dynamics Options Package for Surfacing.

CNC Memory, 5.1 GB (P12 & P77) (O)

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). Extends the internal CNC memory by 1.8 GB.

DXF Reader (P56) (O)

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.

Measuring Cycles for Drilling/Milling (P28) (O)

Enables you to use a probe within the Auto Mode operation. Insert a probing canned cycle to measure tool wear for the SINUMERIK ONE to apply compensation. You can also measure part features and apply adjustments to either work offsets or tool compensation. The cycle can be programmed to command the control to re-machine features based on the result of the measurement. The probing cycle may be combined with a series of logic statements to give you even more flexibility.

Use this powerful feature to:

  • Measure your casting before machining and overcome variations applying offsets to each part
  • Run lights out – even when parts vary
  • Output an inspection report after each machined part
  • Detect tool breakage and switch to sister tool

Execution from External Storage (P75) (O)

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.

Residual Material Detection (P13) (O)

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.

Shopmill (P17) (O)

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.

Simultaneous 3D Run (P22) (O)

3D Solid model graphics real time while running a program. It is a great way to check the progress of your job, especially when you are running a lot of coolant.

TRACYL/Cylinder Surface Transformation (M27) (O)

Wraps a 2D shape around a cylinder, enabling you to program features onto a cylinder using the 4th Axis option of your VMCsi machine.

Handwheel Run - SINUMERIK ONE

Handwheel Run (M08) (O)

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!
