Let’s get serious…about thread rolling. This video from Tesker Manufacturing Corporation shows a thread rolling machine that is capable of rolling threads in stock up to 12″ in diameter. The thread they roll in this video is a 4.5″ x 1 TPI single start ACME in 1045 Cold Drawn Steel. Now THAT is a serious thread.
The Basics Of Electrical Discharge Machining (EDM)
Reliable EDM has a series of videos available on Electrical Discharge Machining or EDM. The company president, Carl Sommer, presents this video that introduces the three types of EDM: wire EDM; ram/sinker EDM; and small hole EDM. The most interesting part of the video is the skim cut being made by wire EDM out of the bath. You can see …
Making Bikes..And Riding Them Too
Here is something fun as we head into the weekend. Yannick Granieri and Sam Reynolds visit Polygon bikes in Indonesia to see how their sponsor makes the machines they ride. OK, so there is all of one minute of manufacturing in this video but it is interesting to see how manual the operation at Polygon is, let alone the apparent …
March Light Painting Inspiration Gallery
While you’re waiting for me to get my act into gear and produce the video for my Physiogram Light Painting with a 2-pendulum Harmonograph you can have a look at what I found inspirational from Flickr in March. It’s a little late, but I am playing catch up still.
Automation Of Water Transfer Printing
A few months ago we looked at the manual application of hydrographics, a process also known as water transfer printing. I noted at the end of that post it was possible to automate the water transfer printing process. Here is a video of a water transfer printing machine that provides automation to the process. This machine feeds a continuous roll …
Physiograms Using A 2-Pendulum Harmonogaph
I recently made a rough, 2-pendulum harmonograph for light painting physiograms. The harmonograph has multiple positions for placing LEDs so I tried making physiograms using 1 or 2 LEDs. Check out the gallery of physiogram patterns I made with below. My plan is to create a video to show you haw I made the harmonograph and how the physiograms were created with …
Lost Foam Casting
Today’s video shows the complete lost foam casting process. One of the advantages to this process as compared to other casting processes is there is no need for draft to be designed into the part. This makes the cast part a near net shape which is mass and material optimised as well as reducing the need for machining operations to …
Sheet Metal Stamping Fundamentals: Dies And Processes
This video from the Society of Manufacturing Engineers takes us through the fundamentals of dies and processes used in the sheet metal stamping operations. The video looks at single and multiple station stamping operations. Single Station Stamping Processes Compound Dies – used for only shearing operations such as cutting and hole punching. Combination Dies – combines shearing operations with forming or shaping operations in a …
Manual Metal Spinning
Here is an interesting video of a manual metal spinning operation. It shows a nose cone for a wind vane being made. This form is somewhat simple and much more complex shapes can be manufactured with metal spinning. Whilst automated or CNC metal spinning operations are available these days it is good to see how these processes are done by …
Has Ford Developed The Most Flexible Sheet Metal Forming Process?
Just when you thought that sheet metal forming technology couldn’t progress much further Ford Motor Company has managed to almost re-invent the wheel. The machine shown in their video below is called ‘Ford Freeform Fabrication Technology’ (F3T) and is a cross between a sheet metal press tool and a 3D printer. The machine uses a pair of opposed delta robots where the upper robot …
