Rolling A Large ACME Thread

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.

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 …

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 …

Carbon3D Is Changing The 3D Printing Game

In a recent TED talk Joseph DeSimone presented a new additive manufacturing technology developed by his company Carbon3D along with a team of scientists from the University of North Carolina and North Carolina State University). They call their 3D printing technology Continuous Liquid Interface Production (CLIP). This new technology utilises photopolymerisation of UV curable resin commonly seen in Stereolithography (SLA) …
