A few weeks ago we revealed 3 silly mechanical design mistakes that you must avoid. Good news – here are 3 more for you! Not everything about mechanical design can possibly taught at university, especially real-world experience. I’ve made plenty of mistakes in my time and here are 3 classic mechanical engineering mistakes you can learn …
3 More Really Obvious Mechanical Engineering Mistakes You Must Avoid Read More »
One of the silliest mechanical design mistakes I made was to mis-position a PCB supporting feature on an injection moulding by around 3mm. Despite this humungous error, it still provided just enough support and the product miraculously passed its drop test. Engineering by luck! I made this error when I was a graduate trainee, and …
A warm welcome to EngineeringClicks. This is the new version of Mechanical Design Forum. We felt it was time for a complete reinvention with a new name, new design and completely revamped site architecture! Mechanical Design Forum (MDF) ran from 2009 to today (29th May 2016), so it had a pretty good run. It has been a …
Aluminium alloy wheels manufacturing process have developed a lot since 1970s. Due to sophisticated wheels design, casting has become the dominant manufacturing process. Alloy wheel material has evolved too: car wheels alloys now contain 7 to 12% silicon content, and varying contents of magnesium in addition to aluminium, in order to meet the demand for …

Electro-Discharge Machining (EDM) is machining with sparks. The work-piece is held in a jig submerged in a dielectric fluid such as kerosene. A power supply generates rapid electric pulses that create a discharge between the work piece and an electrode (a continuous wire or a shaped graphite form) at the point at which the two …
I’ve recently been trying to build up a folder containing images of thermal management solutions – very handy to dip into when trying to come up with ideas for a project! Today a Playstation 2 fell into my hands and naturally I couldn’t help reaching for the screwdriver. I thought I’d share the pics of …
Laser Beam Machining: A coherent beam of monochromatic light is focused on the workpiece causing material removal by vaporisation. Machines are generally CAD/CAM compatible, with 3-axis and 5-axis machines being generally available. Profile creation of sheet metal parts is the most common applications, but it is also possible to drill holes and create blind features …
Wire EDM (Wire Electro Discharge Machining, or WEDM) involves a continuously spooling conductive wire (the most widely used is brass). A power supply generates rapid electric pulses that create a discharge between the workpiece and electrode (the wire). The discharge causes the melting, and probably the vaporisation, of a minute piece of material, slowly eating into …
The tool, which is a negative of the workpiece, is vibrated at around 20KHz with and amplitude of between 0.013mm and 0.1mm in abrasive slurry at the workpiece surface. Material removal is by 3 mechanisms: Hammering of grit against the surface by the tool. Impact of free abrasive grit particles (erosion). Micro-cavitation. Parts are burr-free …
Plasma Arc Cutting is a metal cutting process that uses a high temperature stream of ionised gas through a water-cooled nozzle at very high velocity. An arc is formed between the electrode and the workpiece, which is constricted by a fine bore copper nozzle. Oxygen oxidises the workpiece material, and it is melted by the …
The electric guitar industry can be described as a closed industry. It is difficult to get new ideas accepted in a field that is already overburdened with products (instruments and accessories). The electric guitar is difficult to define as a product. It can be said that it is an instrument of craftsmanship so shrouded with …
