Siemens Digital Industries Software has launched three technology packages exclusively for its Sinumerik One CNC control system. The Sinumerik One Dynamics packages are available in three different variants: One Dynamics Operate, One Dynamics three-axis milling and One Dynamics five-axis milling. The software functions contained in each technology package are said to support users from machine-oriented programming in the job shop to high-performance machining of CAD/CAM-programmed workpieces with high surface quality.

The One Dynamics Operate package supports the machine tool user in efficient programming in the machine shop with Sinumerik’s machining cycles and high-quality CNC simulation for milling and turning applications. In addition, the user is given a wide range of options for accessing NC programs and workpiece documentation. Users have the option of paperless manufacturing and can, for example, visualize 3D CAD data on the shop floor within a short time. For the execution of CAM-generated CNC programs for free-form surface machining, One Dynamics three- and five-axis milling packages offer the Top Surface and Top Speed Plus CNC functions for optimized motion control and improved workpiece surfaces.

With Top Surface, the geometric data from the CAM system is checked and optimized during processing on the CNC using an intelligent algorithm, ensuring high surface quality when milling complex free-form surfaces. Simens notes that this is particularly advantageous for geometrically complex mold components that place special demands on surface quality, mold accuracy and production efficiency—for example, in tool and moldmaking, aircraft construction or medical technology. Top Speed Plus ensures with new filter technology with increased dynamics are made possible without activating mechanical vibrations of the machine and that the contour accuracy is reliably maintained. Depending upon the specific application, this can reduce machining times by up to 30%. As a result, unit costs for milling with CAM-generated CNC programs can be reduced and production efficiency increased.

With a few exceptions, Siemens says the functions of Sinumerik One Dynamics do not require any commissioning effort by the machine tool builder. Once activated, they are available to the user for immediate use on the CNC machine. Since they are CNC software functions, no intervention at the machine or in the machine’s mechanics is required. For users who have challenging requirements when it comes to machining quality and speed, the machine tool builder can add additional optional CNC functions of the Sinumerik control that go beyond the Sinumerik One Dynamics packages. These additional functions must then be activated and parameterized by the machine builder for the user’s individual machine and adapted to the machine statics and dynamics.

  • How to Choose the Right CNC Router

    With moldmaking the focus is on injection molding or other mold types that use wire EDM or CNC machining centers to create the mold components. Your typical machining center weighs several tons and has a relatively small working envelope compared to a CNC router. The mill’s massive construction lends itself to machining rigid materials with very tight tolerances. While this type of CNC is suited for injection molding components, it isn’t always the ideal tool for the job when we broaden our scope of moldmaking and the current opportunities in the marketplace
