Sometimes the question arises to what extent cryogenic cooling is environmentally-friendly, as the gases used are a consumable, unlike other refrigerants that can be reused. Cryogenic processing does have interesting environmental advantages.
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.
The arrival of machine hammer peening opens the way to fast finishing of large milled injection and deep drawing moulds. Instead of manual polishing, an industrial robot does the work in a shorter time. This process also offers a number of other advantages.
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.
Because of their extreme hardness, ceramic materials and their composites are very popular for mechanical applications that are susceptible to wear and tear due to heavy loads. The other side of the coin is that conventional techniques do not usually suffice to work these materials. Some are even impossible to grind, because oxides deposit on the grinding wheel.
Integrated laser hardening offers a solution for hardening slim, elongated objects which suffer deformations with traditional hardening methods. This process also offers a number other advantages.
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.
The combination of laser ablation and micro-EDM is a recent development for the quick finishing of products with small details in hard materials, such as nozzles for diesel engines. EDM is used to remove larger volumes, while laser ablation is used for the fine details.
Femtosecond lasers are ultra-fast pulsed lasers, which are used to remove material. The material is not heated, but immediately turns into a plasma. In addition, the technology is extremely suited for the very precise application of functionalities via textures.
Our consortium partner, Sirris, was given the opportunity to make temporary use of a KMR iiwa with the aim to extensively test and explore the potential of a mobile cobot.
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.
Cryogenic cooling during machining stands for machining at very low temperatures. This has advantages both for tools made of heat-resistant materials, where the heat can be high during machining, and for the machining of softer materials, which will flow more easily during machining.
Solid carbide endmills are the most commonly used tools in almost every machine shop. Process engineers are always concerned with productivity gains by reducing the tooling cost, machining time and bring down the cost per part to increase the margins. The selection of the machining conditions either rely on the experience of the operator or the recommendations from the tool manufacturer.
Almost 10 years after the introduction of cryogenic machining, a lot of research has been conducted on this technology, its application and pros and cons. However, despite the positive results, the step to the industry does not seem to be so obvious.
Manufacturing operations introduce Residual Stresses (RS) during sequential thermo-mechanical processes, like forming, heat-treatment and machining.
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.
Since the launch of Industry4.0 initiative and with the desire to improve product development, product-lifecycle-management (PLM) technologies have been slowly evolving in the background.
Go into 10 different engineering companies and ask questions around how they handle and manage their tools?
Most probably you will receive 10 different answers. Why? Because everybody does it differently.
Definition
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.
When you hear AR, for sure you are thinking about the heavy, chunky, massively overpriced Hololens and how you tried to somehow see something with the small field of view. We don’t even have to talk about the hard time you had trying to tap on virtual objects in the air.
Developments and advancements in digital technologies have challenged traditional manufacturing and become the basis of what is known as the Fourth Industrial Revolution or Industry 4.0.
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.
Tool wear describes the gradual failure of cutting tools due to regular operation. It is a term often associated with tools used for example on turning, milling, drilling and other types of machining operations where chips are made. We could also say “We started with a new cutting edge and at the beginning of the operation everything was working well.
Graphite has specific properties that make machining a challenge. It’s strong, but also brittle, and is susceptible to chipping if not handled properly. Cutting Graphite (or carbon) is different from cutting Metals. Metal exerts plastic deformation when a tool edge cuts it producing a curl or chips.
The first spinning-tool technology was developed jointly by Mori Seiki and Kennametal around 2008.
Tap testing, also known as modal testing, is an experimental method that is used to excite the machine-tool system in order to extract its harmonic information such as natural frequencies, modal masses, modal damping ratios and mode shapes. This is normally done in static conditions, using the impact hammer as the excitation mechanism, and an accelerometer as the sensor. In theory, the tool t
Small and medium machining shops are often arranged as job-shops. In a job-shop the production is usually done in small batches, and the machines are arranged in functional units, or cells (milling cell, drilling cell, etc). Each part or product to manufacture needs to follow a sequence of operations (a route) to be performed in different machines.
Residual stresses are generated in a part during manufacturing which typically involves sequential thermo-mechanical processing including forming and heat-treatment steps.
Computer Aided Design (CAD) and Computer Aided Manufacture (CAM) software has been developed since the late 1950s and is an essential component of modern manufacturing. The term CAD covers a range of applications from 2D drafting packages to full 3D design packages with simulation and analysis tools.
Model Based Definition is a new strategy of product lifecycle management in which the CAD models (Computer aided design) change from simple models with only the geometric data to extensive information sources containing all product manufacturing information (Alemanni, Destefanis, & Vezzetti, 2010).
How does it work?
By use of a head mounted display and a set of controllers, the user is placed in a virtual environment where they can practice, learn and improve their skills. The user will enter a scenario in which they have to perform a set of tasks to reach a goal. The scenario depends on the type of training.
The use of ceramic cutting tools is on the rise, that news is less dramatic than it seems, because solid ceramic end mills and inserts are usually easier to use than carbide tools. Changing to using ceramic cutting tools doesn’t need really any special process changes. Contrary to what people might think about ceramic tooling.
A sensory tool holder is an inline tooling adapter that is capable of measuring three different dynamic responses within the tool – these being the bending moment, the tension and the torsion. With applications to both milling and turning operations, a sensory tool holder can continually collect data during a given operation and wirelessly transmits this data to a nearby laptop.
