Residual stresses are inherently introduced to forged products during their deformation. These stresses influence the integrity of load-bearing parts. Their effects depend on their nature (tensile or compressive), location and magnitude.
Hot-forging dies should display high strength, toughness and low wear. Plastic deformation and wear of the dies lead to their costly refitting or disposal. This article analyzes the role of circumferential press-fit rings on the plastic deformation and wear of a die employed in the production of spherical milling bodies.
As forging hammers have become faster and more powerful, so too has the need to isolate their vibrations. This article examines ways of isolating or minimizing vibration transfer to the shop floor, employees and adjacent equipment.
In the past, the proper induction heating of forging billets presented challenges to the forger that could only be resolved through trial and error. Now, by using advanced computer simulations to model the heating and forging processes, hot-forging designers have powerful tools to reduce the guesswork and unit costs.
