According to p.33 of this presentation 'bedding in' is a process of packing the molding sand by ramming the sand around and under the pattern until the sand is tightly packed and even with the parting line. There is also a glossary with foundry and casting terms defined here. This is used when the parts to be cast are quite large, often as a step in pit ...

Redundant ; How would you pour with no gravity; the metal would just sit in the ladle after you turn it upside-down. Floating of slag/dross , and hydrogen gas ( always present to some degree) would not happen.

The cutting blanks equation is, $$F=l*t*s$$ L=length mm t+thickness mm s =shear N/mm^2 We measure the perimeter of the blank and then add the circumference of the two holes. $\text{The straight sides are 2*70mm =140mm and 2*( 70-40-20=10)mm=20mm =160mm}$ $\text{half circles are 2*pi*20=125.66mm, inner holes 2*2*pi*15=188.49mm} $ $\text{ Total 188.49+124.66+...

Standard Times are established time measurements used in Industrial Engineering to estimate how long humans take to do something. These are built by breaking down an activity into its core components and applying (usually) pre-determined values for each. Times are in Time Measurement Units (TMU's), which are defined as .036 seconds (27.77 TMU/sec). BAck in ...

I have never seen a cleaning system like this; but it may exist. It may have some merits for having good control and very high purity cleaning; but probably overly complicated for just an adhesive bonding application. Usually manufacturing tries to avoid batch operations when possible to avoid down time. Industry also avoids things that are disposable or ...

I believe your primary goal when transitioning from single prototypes to small batch production should be to improve manufacturability, and ensure that your design is scalable. Examples of parts/systems that may need to be revised: Parts that were made without drawings, for example by match drilling, or "freestyling" Parts that are not easily obtainable in ...
