Part-holding tooling is a fraction of the total press cost, but it has the most effect on whether a stamping press is running at its peak potential. Taking proactive steps in tooling selection, including working with your supplier, using simulation, choosing the best framework material, and choosing the most suitable end-of-arm tooling, can make all the difference.
It is almost unrealistic to expect some stamped part part features, such as hole position and flatness, to remain within a small tolerancing zone.
Robotics gained a foothold in industry because they can work in environments that are hot, toxic, or otherwise dangerous. The drawback was the programming, which initially was tedious and time-consuming, especially for precision tasks such as welding. Advancements in tactile sensing systems, automated arc welding controls, and software for tube and pipe welding have helped to spread robotic welding technology.
Industrial sensors such as movement sensors, angle sensors, contact sensors, are considered common devices, but their use in transfer dies can help stamping companies like Ultra Tool & Manufacturing overcome application challenges.
The automotive suppliers who survived the recent economic crisis are smaller than before and their capability to add capacity has been reduced. With predictions of 15 million cars sold in 2011, this is a big concern.
Yield strength and ultimate tensile strength can be used to determine the flow stress curve. First, the tensile test reveals tensile force and elongation, which are used to obtain the stress-strain curve, which reveals yield stress and ultimate tensile strength.
