Agile tooling

Last updated

Agile tooling is the design and fabrication of manufacturing related-tools such as dies, molds, patterns, jigs and fixtures [1] in a configuration that aims to maximise the tools' performance, minimise manufacturing time and cost, and avoid delay in prototyping. A fully functional agile tooling laboratory consists of CNC milling, turning and routing equipment. It can also include additive manufacturing platforms (such as fused filament fabrication, selective laser sintering, Stereolithography, and direct metal laser sintering), hydroforming, vacuum forming, die casting, stamping, injection molding and welding equipment. [2]

Contents

Agile tooling is similar to rapid tooling, which uses additive manufacturing to make tools or tooling quickly, either directly by making parts that serve as the actual tools or tooling components, such as mold inserts; or indirectly by producing patterns that are in turn used in a secondary process to produce the actual tools. Another similar technique is prototype tooling, where molds, dies and other devices are used to produce prototypes. Rapid manufacturing, and specifically rapid tooling technologies, are earlier in their development than rapid prototyping (RP) technologies, and are often extensions of RP.

The aim of all toolmaking is to catch design errors early in the design process; improve product design better products, reduce product cost, and reduce time to market.

Users

Hundreds of universities and research centers [ example needed ] around the globe are investing in additive manufacturing equipment in order to be positioned to make prototypes and tactile representations of real parts. Few have fully committed the concept of using additive manufacturing (AM) to create manufacturing tools (fixturing, clamps, molds, dies, patterns, negatives, etc.). AM experts[ who? ] seem to agree that tooling is a large, namely untapped market. Deloitte University Press estimated that in 2012 alone, the AM Tooling market $1.2 Billion. At that point in the development cycle of AM Tooling, much of the work was performed under the guise of “let’s try it and see what happens”.

Additive manufacturing, starting with today's infancy period, requires manufacturing firms to be flexible, ever-improving users of all available technologies to remain competitive. Advocates[ who? ] of additive manufacturing also predict that this arc of technological development will counter globalization, as end users will do much of their own manufacturing rather than engage in trade to buy products from other people and corporations. [3] The real integration of the newer additive technologies into commercial production, however, is more a matter of complementing traditional subtractive methods rather than displacing them entirely.

Automotive – approaching niche vehicle markets (making less than 100, 000 vehicles), rather than high production volume

Aircraft – the U.S. aircraft industry operates in an environment where production volumes are relatively low and resulting product costs are relatively high. Agile tooling can be applied in the early design stage of the development cycle to minimize the high cost of redesign.

Medical – cast tooling would benefit a great deal from agile tooling. However, the cost for the tooling may still be significantly greater than the cost of a casting piece, with high lead times. Since only several dozen or several hundred metal parts are needed, the challenge for mass production is still prevalent. A balance between these four areas – quantity, design, material, and speed are key to designing and producing a fully functional product.

Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material, aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. It is similar to selective laser melting; the two are instantiations of the same concept but differ in technical details. SLS is a relatively new technology that so far has mainly been used for rapid prototyping and for low-volume production of component parts. Production roles are expanding as the commercialization of AM technology improves.

A Model maker is a professional Craftsperson who creates a three-dimensional representation of a design or concept. Most products in use and in development today first take form as a model. This "model" may be an exacting duplicate (prototype) of the future design or a simple mock-up of the general shape or concept. Many prototype models are used for testing physical properties of the design, others for usability and marketing studies.

CAD/CAM dentistry is a field of dentistry and prosthodontics using CAD/CAM to improve the design and creation of dental restorations, especially dental prostheses, including crowns, crown lays, veneers, inlays and onlays, fixed dental prostheses (bridges), dental implant supported restorations, dentures, and orthodontic appliances. CAD/CAM technology allows the delivery of a well-fitting, aesthetic, and a durable prostheses for the patient. CAD/CAM complements earlier technologies used for these purposes by any combination of increasing the speed of design and creation; increasing the convenience or simplicity of the design, creation, and insertion processes; and making possible restorations and appliances that otherwise would have been infeasible. Other goals include reducing unit cost and making affordable restorations and appliances that otherwise would have been prohibitively expensive. However, to date, chairside CAD/CAM often involves extra time on the part of the dentist, and the fee is often at least two times higher than for conventional restorative treatments using lab services.

Cast urethanes are similar to injection molding. During the process of injection molding, a hard tool is created. The hard tool, made of an A side and a B side, forms a void within and that void is injected with plastics ranging in material property, durability, and consistency. Plastic cups, dishware, and toys are most commonly made using the process of injection molding because they are common consumer items that need to be produced on a mass scale, and injection molding is designed for mass production.

Digital manufacturing is an integrated approach to manufacturing that is centered around a computer system. The transition to digital manufacturing has become more popular with the rise in the quantity and quality of computer systems in manufacturing plants. As more automated tools have become used in manufacturing plants it has become necessary to model, simulate, and analyze all of the machines, tooling, and input materials in order to optimize the manufacturing process. Overall, digital manufacturing can be seen sharing the same goals as computer-integrated manufacturing (CIM), flexible manufacturing, lean manufacturing, and design for manufacturability (DFM). The main difference is that digital manufacturing was evolved for use in the computerized world.

Material extrusion-based additive manufacturing (EAM) represents one of the seven categories of 3d printing processes, defined by the ISO international standard 17296-2. While it is mostly used for plastics, under the name of FDM or FFF, it can also be used for metals and ceramics. In this AM process category, the feedstock materials are mixtures of a polymeric binder and a fine grain solid powder of metal or ceramic materials. Similar type of feedstock is also used in the Metal Injection Molding (MIM) and in the Ceramic Injection Molding (CIM) processes. The extruder pushes the material towards a heated nozzle thanks to
