NORDLINGEN, Germany—Six-axis robots and a rotary indexing table are the heart of a high-speed automated assembly system that produces 200,000 automotive sensors daily.

It has become fashionable lately for some U.S. companies to tout how they’ve reshored production from overseas. Baldor Electric Co. isn’t one of them—it never left. The company has been manufacturing electric motors, drives, bearings and other motion control products in the United States for decades.

Component interoperability for PC-based vision systems has come a long way in a short time. The main reason for this quick evolution is interface standards, which the AIA, a machine vision trade group, began introducing in 2000.

Robotic screwdriving offers numerous advantages to manufacturers, such as flexibility and repeatability. However, it’s easy to underestimate the requirements of automation. Sometimes, engineers specify the wrong type of robot or overlook parts feeding issues.

Several issues need to be addressed before there will be more widespread use of robotic screwdriving. Cost, robot design, training, culture and other factors must be considered by manufacturing engineers.

CLEMSON, SC—Engineering students at Clemson University have designed a flexible machine that automatically installs O-rings.

Carbon-fiber reinforced composites are popular in the aerospace and marine industries as a lightweight alternative to aluminum, steel and other metals. The material is also used to produce railcars, wind turbine blades and sporting goods.

Industrial fabric curtain walls are growing in popularity. In assembly plants, two of the fastest-growing applications are for lowering noise levels and controlling dust.

Mennie precision-machines transmission and fuel-system parts and assemblies used in mission-critical applications. Customers include Caterpillar, Bosch Rexroth, Saur-Danfoss, Eaton Hydraulics, Poclain Hydraulics, Allison Transmission, American Axle and Cummins.

Assemblers must work quickly while meeting strict quality requirements.
