Flat Metal Doesn't Always Mean Stress Relieved Metal - Fabricating and Metalworking. Whether it's coming from a service center or an upstream process, most sheet or plate will contain residual stress, as shown in left sample, compared to same material (on right) after processing in a parts leveler.
The servo-hydraulic leveler adjusts its force instantly to compensate for the varying cross section of parts with large cutouts and perforations, or shapes such as triangles and circles. Comparison of leveled and unleveled sheet metal after robotic welding. A free-standing servo-hydraulic leveler integrates easily into fab shop workflow to supply stress-free parts for bending, assembly or welding. “The material coming from a service center has probably been leveled at some point, but most metals retain internal stresses and a degree of coil defects that make setup, processing or assembly difficult downstream,” says Nicholas Miller, the technical director at ARKU Coil Systems (Cincinnati, OH).
“And it doesn’t take an expert to achieve great results on the first pass. Transforming the Way Material is Cut - Fabricating and Metalworking. A review of some of the newest laser cutting systems, laser marking equipment, and related accessories and services now on the market.
The Laser Next from Prima Power offers the best dynamic performance of any 3D laser on the market, with 208 m/minute trajectory speed and 2.1 g acceleration. The JENOPTIK-VOTAN BIM laser machine is primarily used in the automotive industry to cut highly complex 3D car body parts and structural parts as well as hydroformed tubes, e.g. for exhaust systems, precisely and quickly. Manufacturers can also benefit greatly from its dynamic capability laser cut contours and functional holes in white goods, tanks and containers. As a highly productive, universal machine, the TruLaser 5030 fiber from TRUMPF is able to process complex contours and thin sheets while keeping the cost per part to a minimum. The optional laser bevel head on the Alpharex from ESAB allows fully automated variable bevel angle contour cutting from 0 to 45 deg. Machining. Jakobs gear hobbing machine. Työstöarvot.

Jacobs Gear Hobber. An interesting article I've stumbled across recently is "A Gear Cutting Machine" by T.D.
Jacobs in Model Engineer, January through August 1976. This looks like an interesting long term back burner project, utilising structural steel mainly and some bar stock. I plan to use castings instead of structural steel, so if it doesn't work out, I can simply melt it into something else ;-) Jacobs describes the construction of the machine in seven sections, so I will try and work through it in that order. An extra couple of sections have been added, namely electrical and links/resources. The original article is sketchy about some details (for example how to hold the gears onto the shafts), an attempt will be made to fill the gap through these pages.
