Siemens’ Integrated CAD/CAM/CNC Process Chain for Medical Part Manufacturing
Siemens announced the introduction of CNC solutions designed specifically for the medical industry. These CNC solutions featuring the Sinumerik® 840D sl CNC, the Sinamics® S120 drive system and high performance motors enable machine tool users to create CAD/CAM data with NX CAM, as well as a system platform for high-speed cutting.
Medical part manufacturing is, first and foremost, based upon perfected cutting technologies. The manufacture of medical implants and prostheses requires, above all, high-precision machining with a short machining time that must produce perfect surfaces. Such high-precision, high-speed cutting is based on an integrated, high-performance CNC solution. This covers the creation of CAD/CAM data, straightforward programming, set-up on the CNC, suitable probes and high-precision milling with innovative tools.
High-speed cutting is technically very demanding, precisely because of the high speeds involved. Siemens CNC solutions for these types of milling tasks have correspondingly high spindle speeds and feed rates. These features are essential for the manufacturing of high-quality medical products, such as tooth and bone implants, bone screws and hip prostheses. The interactions between its many and varied functions enables Sinumerik to be adapted flexibly to meet the changing demands of CNC production. These functions include the exact measurement and calibration of multi-axes kinematics and the coupled motion of the tool orientation. Innovative technologies enable medical engineering products to be matched precisely to a patient’s individual requirements.
In order to enable manufacturers to react quickly and easily to changing market needs as well as increases in batch production, Siemens is offering a wide range of setup functions for machine retrofit. All the important tool-related data is saved and can be recalled later in a single step. Jerk limitation, pre-control and the perfected “look ahead” function all support the operator during tool- and mold-making. Sinumerik Safety Integrated also facilitates the implementation of highly-effective operator and machine protection concepts.
