Medical implants range from a wide array of materials including metals, metallic alloys, plastic polymers, ceramics, hydrogels, and composites depending on the use-case. They often fixed into tissues with glues and therefore must be compatible with the host body.
With the development of high-resistance and refractory materials in the medical, energy and aeronautics sectors, a review of machining processes is urgently needed.
The Reach and ROHS directives, as they are currently being developed, foresee the prohibition of the use of certain harmful or dangerous substances, including lead, even as an alloying element.
Abrasive water jet turning is a reducing technology that uses a high pressure water jet with granules - read: ‘abrasive’ - particles. How does it actually work? Water and particles are mixed together to become a high pressure water jet in the spray nozzle.
To be heard on the international level, better do it together. Such is the meaning of all the standardization efforts led by Cetim with all its professional mechanical engineering commissions.
Grinding through electrolytic in-process dressing (or ‘ELID’ for short) is an efficient technique for processing extremely hard and brittle materials such as ceramics (ZrO2, Si3N4), cermets and hardened steel. This grinding technique allows metal-bound grinding discs to be used, which are after all highly durable and difficult to adjust compared with discs with resins or glass.
Within the automotive sector, new gear prototypes must be produced continuously, for which conventional production methods are not efficient. A possible alternative is selective laser hardening, integrated on a production centre that also performs other operations on the gears.
Manufacturing operations introduce Residual Stresses (RS) during sequential thermo-mechanical processes, like forming, heat-treatment and machining.
Importance and potential of knife engineering
3D measuring probes prove to be extremely suitable for a quick check of the kinematics of a five-axis milling machine. The principle is based on measuring an object, by means of an accurate measuring probe, according to pre-programmed measuring cycles.
Designed from various results of Cetim's generic and sectorial R&D, this guide is composed of a set of sheets which aim at providing good practices in the field of cutting fluids.
Three photonic laser techniques to transfer colour images with high resolution to metal surfaces: oxidation of metal and interferences, formation of nanoparticles and plasmon resonance, structuring of a periodic circuit and diffraction of light.
This technical book is not intended to be an exhaustive treatment of all the subjects and problems inherent in machining by material removal.
With high-speed rough milling, correct programming can prevent exceeding the limit value of the radial cutting width and breaking the tool. In curves and transitions, however, the cutting width can temporarily increase, while this is not what is needed.
Grinding is a process of machining a flat, cylindrical or curved surface (profile grinding) where material is removed by abrasion. The original purpose of this operation was to improve the surface finish of highly hardened parts.
The pricing of a product has a large influence on the sales revenue and the profit. Surprisingly, research shows that a more accurate cost estimation does not automatically lead to a higher profit.
This watch file presents the evolutions of ranges in the field of machining. The machine tools and peripheral technologies presented during the global industrie show are described by our Cetim speaker.
The change in the market forces machining companies to update product design, complexity, quality, durability and delivery times. This is made possible by the development of computer technology. During the development of a 3D model in CAD (Computer Aided Design), data can be adjusted quickly.
Let’s cut to the chase: not every SME needs extra MES functionality to link the office and the shop floor, provided that the available ERP modules and possibilities are fully utilised. Because ERP makers also want to claim a part of the MES market, many traditionally have a shop floor module at their disposal.
Due to the expected increase in complexity in production, demographic change and the decreasing product life cycles, industrial companies have to face many challenges.
Efficiency of machines has been an important topic in many areas of industry, at least since the introduction of the term "Industry 4.0". One of the challenges to improve the efficiency of industrial plants is the implementation of anomaly detection systems.
Machining by ion dissolution, an opportunity for polishing implants.
Electro Chemical Machining (ECM) is a well-know technique: the shape of an electrode is reproduced in the part by current action.
