New lead screw configurator allows for quick design
igus has developed a new lead screw configurator that allows customers to design their own lead screw and associated drawing in minutes without in-depth technical knowledge and CAD software. The new tool even directly checks the plausibility of the configuration. Trapezoidal, high helix, or metric thread lead screws in combination with nuts made of iglide high-performance polymers ensure lubrication-free adjustment for long-lasting and smooth-running applications. The company runs its North American operations out of Providence, RI.

Resins: Alkali stress crack resistance for automotive
The Polyplastics Group recently introduced a new polybutylene terephthalate (PBT) resin that delivers excellent alkali stress crack resistance for a range of automotive applications. DURANEX 532AR also exhibits outstanding hydrolysis, heat shock resistance, and electrical performance for components in the chassis and engine compartment. This material has successfully reduced the risk of cracking in molded articles by preventing alkali (often formed by rust on metal parts) from penetrating the inside of the resin, thus imparting toughness that helps generate less stress. Ideal for use in parts (like electrical components and sensors) installed in the chassis section and lower areas of vehicles.

Top Product: Cross roller ring can swing the loads
Because it has orthogonally arranged cylindrical rollers, the cross roller ring from THK is a roller bearing with high rotation accuracy capable of bearing loads in every direction. Cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90-deg V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including radial, axial, and moment loads. This component is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments, and IC manufacturing machines. Available in several rotation configurations including inner/outer ring, inner ring only, and outer ring only. And now a new micro cross roller ring is perfect to handle smaller applications.

Lightweight, heavy-duty thermoplastic planks introduced
If you're told to walk the plank these days, you may find yourself walking on plastic. SABIC recently introduced its STADECK heavy-duty panels to the Americas. These high-strength but extremely lightweight panels are used for scaffolding and numerous other applications in the building and construction industries. They are made from glass fiber-reinforced thermoplastic resin and are up to 60 percent lighter than wooden planks, saving not only your back but also the gas or diesel it takes to tote heavier support materials around. They also never rot or corrode.

Plastic torque-limiting wing nuts
JW Winco, a leading supplier of standard industrial machine components, has now made available EN 5320 Plastic Torque Limiting Wing Nuts, which are used when manually applied torque is to be limited. Turn clockwise, and the torque of the wing nut triggers an "over-engagement" when the specified torque is reached. When tightening, this will ensure the maximum permissible torque is not exceeded. Turn counter-clockwise, and the torque needed for loosening will always be transmitted properly. The technopolymer plastic is glass fiber reinforced and temperature resistant up to 176 F (80 C). The wing nuts are available in either a black matte or orange matte finish. An aluminum version (GN 3663) is also available.

Ford reduces production line injury rate by 70 percent using virtual manufacturing and ergonomists
Ford Motor Company has reduced its production-line injury rate by 70 percent since 2003 for its more than 50,000 "industrial athletes" by using virtual manufacturing, new ergonomics technology, lift-assist devices, workstation redesign, and data-driven process changes.
"We refer to our assembly line employees as 'industrial athletes' due to the physical nature of the job," says Allison Stephens, technical leader for assembly ergonomics at Ford. "We have made data-driven decisions through ergonomics testing that has led to safer vehicle production processes and resulted in greater protection for our employees."
At Ford, immersive virtual reality uses a 23-camera motion-capture system and head-mounted display to virtually immerse an employee in a future workstation. Then, the employee's movements are evaluated to determine task feasibility and proficiency.
While automotive designers focus on a vehicle's look and the customer experience, Ford virtual manufacturing experts focus on two key areas: design feasibility and the safety of employees on the production line.
Two to three years in advance of a new-vehicle launch, Ford ergonomists virtually simulate the build process using both human and virtual test subjects to assess the physical labor needed to build a vehicle. In an effort to reduce and help prevent employee fatigue, strain, and injury, the data collected is used to guide engineering solutions prior to implementing tasks on the production floor.
3D printing is used by an ergonomist to validate hand clearance in the vehicle assembly process in those instances in which virtual simulation yields unclear results. Employees with various hand sizes use the 3D-printed model to test how tight the space will be in vehicle assembly, which helps to drive better production decisions.
Core virtual manufacturing technologies
On average, Ford ergonomists complete more than 900 virtual assembly task assessments per new-vehicle launch centered on three core technologies: full-body motion capture, 3D printing, and immersive virtual reality. Each provides critical data used to evaluate the overall safety of the assembly process for employees, while maintaining high vehicle quality for customers.
Virtual manufacturing experts at Ford use:
- Full-body motion capture provides data on how an employee uses his or her body to move and complete tasks. Through more than 52 motion-capture markers placed on an employee's arms, back, legs, and torso, ergonomists can record more than 5,000 data points to evaluate muscle strength and weakness, joint strain, and body imbalance. Similar technology is used across professional sports to improve athletes' techniques and help them avoid injury.
- 3D printing is used by an ergonomist to validate hand clearance in the vehicle assembly process in those instances where virtual simulation yields unclear results. Employees with various hand sizes use the 3D-printed model to test how tight the space will be in vehicle assembly, which helps to drive better production decisions.
- Immersive virtual reality uses a 23-camera motion-capture system and head-mounted display to virtually immerse an employee in a future workstation. Then, the employee's movements are evaluated to determine task feasibility and proficiency.
Full-body motion capture provides data on how an employee uses his or her body to move and complete tasks.
"Motion tracking technology has been used for more than 30 years to quantifiably assess the technique of athletes and reveal where they may be susceptible to injury from overuse or from forces that will damage tissues," says Gary Scheirman, vice president for applications engineering, Motion Analysis Corp. "Using similar technology, Ford can develop state-of-the-art, safe working environments for its employees and produce better vehicles for its customers."
Virtual manufacturing program results
To date, Ford ergonomists have worked on more than 100 new-vehicle launches globally using virtual manufacturing tools -- most recently the 2015 Ford Mustang, F-150, Edge, and 2016 Explorer. Through significant investments in the program, not only has Ford achieved a reduction in employee injury rates, it has seen a 90 percent reduction in such ergonomic issues as overextended movements, difficult hand clearance, and tasks involving hard-to-install parts.
