Technology Packages Support Motion Control, Workpiece Quality for Moldmaking Applications

Siemens Digital Industries Software recently launched what it says are three powerful technology packages exclusively for its new Sinumerik One 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 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 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 very short time, according to the company. For the execution of CAM-generated CNC programs for freeform 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 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. This reportedly ensures high surface quality when milling complex freeform surfaces. Siemens says 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 that 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, Siemens contends that this can reduce machining times by up to 30%. 

Moreover, for users who have particularly 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, according to Siemens.
