Why Use a Single Flute End Mill?

by Bob There are a lot of strange beasts out there in the cutting tool world, and a lot of physics that are not obvious. For example, many machinists will know that more flutes means more productivity, but that certain materials, like aluminum, require fewer flutes–usually two or three. If that’s the case, when would it ever make sense to use a single flute end mill? Is there a time when the least number of flutes possible is a good idea? In a word, “Yes!” Let’s talk about why. The reason we use fewer flutes in some materials has to do with the behavior of chips inthose materials. Simply put, aluminum creates bigger chips, all other things being equal. This has to do with the way the material curls as well as other factors. The space created by the flutes of the endmill is where the chips have to go as they’re being cut. If there is not enough space relative to the volume of the chips, you’re going to have problems and may wind up with a broken cutter. Therefore, we typically dial back the number of flutes for aluminum because it creates a larger volume of flute space

High-tech from Augsburg featured in the new James Bond film

Innovative 3D printing technology from Augsburg-based voxeljet is on display in the newest James Bond film Skyfall – more specifically in the scene when James Bond’s car explodes in flames. A total of three Aston Martin DB5 models were created at the company’s service centre; the models double for the now priceless original vehicle from the 1960s in the film’s action scenes. Action scenes in expensive film production such as a James Bond films must look as realistic as possible. For the model builders working behind the scenes, the high demands of film makers translate into more requirements and detail work. Therefore companies such as Propshop Modelmakers Ltd, which specialises in the production of film props, are always on the look-out for trend-setting manufacturing methods. The fact that the British company selected the 3D printing technology of a German provider is a special honour for the Augsburg company. “Of course only state-of-the-art technology is used for a new James Bond film. To be considered a benchmark by the model builders from the Pinewood Studios is evidence of the performance and position of our 3D printing system in terms of global ranking,” says voxeljet CEO Dr. Ingo Ederer. voxeljet is considered

VXC800: Premiere for the world’s first continuous 3D printer

From study to series production readiness With an innovative concept study of the world’s first continuous 3D printer, voxeljet garnered considerable attention at GIFA 2011 – and elicited an outstanding response from the expert audience. Now, the Augsburg-based equipment builder is presenting the brand new VXC800, a 3D continuous printer that has been developed to series production readiness. The machine will celebrate its premiere at EuroMold 2012. “Our presentation of the concept study was so well received that we decided on a rapid implementation of the project. Our development team worked at full speed for an entire year. The result is the VXC800 – the world’s first continuous 3D printer that lays the foundation for a completely new generation of equipment. The building and unpacking process steps now run in parallel, without a need to interrupt the operations of the system – an absolute novelty for the industry,” says Dr. Ingo Ederer, CEO of voxeljet technology. The advantages of this unique concept are clear: The innovative system design allows for hitherto unprecedented performance and flexibility. While the printing process is active on one side of the system, unpacking can take place simultaneously on the other side. All of this can

How 3D Printing works

The Vision, Innovation and Technologies Behind Inkjet 3D Printing Introduction As every designer knows, there’s magic in transforming a great idea into a tangible and useful object you can hold in your hand. It can be a consumer good on a store shelf, a critical component of an industrial machine, or even an early physical prototype that unveils your new idea to the world. Physical prototypes — basic and blocky or wonderfully realized in shape, texture and color — go far beyond drawings or computer models to communicate your vision in a dramatic way. They empower the observer to investigate the product and interact with it rather than simply guess what it might be like. Before the product is ever produced, people can touch it; feel it; turn it left, right and upside down; and look inside. They can test it, operate it and fully evaluate it — long before the finished product is brought to market. Until recently, a quick and affordable physical prototype has been an oxymoron. Obtaining prototypes wasn’t quick. it meant contracting with a fabricator who handcrafted them or used a complicated stereolithography machine. in either case, it took weeks, and it wasn’t affordable. You were

Concept Laser Mould inserts with close-contour cooling and a hybrid build style Schleiz

Application-oriented laser melting at LPT Mould inserts with close-contour cooling and a hybrid build style Schleiz, 18.10.2010: Cores, cavities and moulds require constant care and maintenance to remain fully operational and productive. Mould makers and plastics processors are increasingly opting for flexible and technically accomplished service providers. We went to LPT to find out more information and spoke to the founder and senior partner Erwin Gottschall about laser welding, laser melting and laser engraving for German mould-making and tool-making. Erwin Gottschall founded LPT in Paderborn in 1995 to provide working resources in metal, aluminium and special materials. It very quickly became apparent that mould-makers are shirking welding, but like to make use of this as a service. In addition, Gottschall recognised the significance of laser technology at a very early stage and relied on the fact that the mould-maker generally does not wish to apply the process of generative laser melting itself. Firstly this is because the technology requires specific knowledge and secondly also because capacitively it cannot always be used in an economically viable way by the mould-makers. LPT filled this gap in the market. 12 branch offices and a technical facility for metal laser melting in Schleiz now

The rapid and efficient method for sand casting moulds

The tool-less production of moulds using 3D print technology The rapid and efficient method for sand casting moulds What began in the automotive industry is now continuing in many other industrial sectors – the triumphant success of 3D print technology. More and more users value the time and cost advantages offered by this process for the tool-less production of sand moulds for metal casting. And they benefit from the newest developments of this fairly new technology.   Cast parts in small batch sizes are very popular. While it used to be mainly automotive manufacturers and suppliers that required very small quantities of metal cast assemblies and components for testing and prototype manufacture and discovered 3D printing as a superior technology for producing the required sand cores and moulds, this method has since established itself in numerous other industrial segments. Today, 3D printing is used in conventional applications and all other situations that require the rapid and efficient production of sand moulds – whether for architecture, restorations, aviation and aerospace or the production of designer furniture. The technology’s breakthrough has not gone unnoticed at the service centre of voxeljet technology GmbH. This is where state-of-the-art 3D printing systems create high-quality sand
