An analysis of injury/illness records and survey data identified upholsterers and workers in the machine room as two occupations within the industry at elevated risk for low back injury. A detailed ergonomic evaluation of the activities performed by these workers was then performed and the high risk subtasks were identified. The analysis for upholsterers revealed: (1) high forces during the loading and unloading of the furniture to and from the upholstery bucks, (2) static awkward postures (extremeflexion>50°, lateralbending>20°, twisting>20°) during the upholstering of the furniture, and (3) repetitive bending and twisting throughout the operation. For machine room workers, this ergonomic evaluation revealed repetitive bending and twisting (up to 5 lifts/min and sagittal flexion>80°, lateral bending>15°, twisting>45°) when getting wooden components from or moving them to the shop carts that are used to transport these materials. Engineering interventions were then developed and evaluated in the laboratory to document the reduction of exposure to these stressors. The height-adjustable upholstery buck system eliminated the lifting and lowering requirements and affected trunk kinematics during the upholstery operation by reducing peak sagittal angles by up to 79% (average: 52%; range: 27–79%), peak sagittal accelerations by up to 42% (average: 71%; range: 0–74%) and peak lateral position by up to 31% (average: 20%; range: 12–31%), and showed no impact on time to complete the task. The machine room lift reduced peak sagittal angle by up to 90% (average: 76%; range: 64–90%), peak sagittal accelerations by up to 86% (average: 72%; range: 59–86%) and had a positive impact on the time to complete the task (average reduction: 19%). The ergonomic intervention research documented in this report shows the impact of engineering controls for the furniture manufacturing industry on the risk factors for work-related low back injuries.}, number={5}, journal={INTERNATIONAL JOURNAL OF INDUSTRIAL ERGONOMICS}, author={Mirka, GA and Smith, C and Shivers, C and Taylor, J}, year={2002}, month={May}, pages={263–273} } @article{mirka_shivers_smith_taylor_2002, title={Ergonomic interventions for the furniture manufacturing industry.

The analysis of OSHA Form 200 logs and surveys of furniture workers revealed that upholsterers, workers who use random orbital sanders and workers who use spray guns are at higher levels of risk of illness than the rest of the working population. An on-site ergonomic analysis of these three jobs was performed and the following risk factors were identified for each of these three work groups: upholsterers—repetitive, high-force pinch grips; sanders—long-duration static grip forces; and sprayers—awkward postures (ulnar wrist deviations and wrist flexion). Engineering interventions in the form of new or modified handtools were then evaluated in the laboratory to assess their effectiveness in reducing exposure to these risk factors. For sanding, an interface was created that secured the hand to the sander with the intention of reducing the need for static grip forces during sanding. A new handtool was created for upholsterers that replaced the repetitive pinch grips with a power grip. Finally, a commercially available spray gun with ergonomic features was evaluated. Each of these modified tools/methods was compared with the standard methods typically used in industry. The results show that most of the intended beneficial effects were realized. The random orbital sander interface reduced extensor muscle activities by an average of 30%. The upholstery handtool reduced the intrinsic hand muscle activities by an average of 51%. The effects of the adapted spray gun were most prominent when working on horizontal surfaces and showed an average reduction of 40° of wrist flexion and 14° of ulnar deviation as compared to the standard pistol grip spray gun in this activity. The ergonomic intervention research described in this report documents a reduction in exposure to risk factors for upper extremity cumulative trauma disorders for three work activities in the furniture manufacturing industry.}, number={5}, journal={INTERNATIONAL JOURNAL OF INDUSTRIAL ERGONOMICS}, author={Mirka, GA and Shivers, C and Smith, C and Taylor, J}, year={2002}, month={May}, pages={275–287} } @article{cormier_taylor_2001, title={A process for solvent welded rapid prototype tooling}, volume={17}, number={1-2}, journal={Robotics and Computer-Integrated Manufacturing}, author={Cormier, D. and Taylor, J.}, year={2001}, pages={151–157} } @article{taylor_cormier_joshi_venkataraman_2001, title={Contoured edge slice generation in rapid prototyping via 5-axis machining}, volume={17}, number={1-2}, journal={Robotics and Computer-Integrated Manufacturing}, author={Taylor, J.

This new system is shown to have a mechanical amplification (leverage) that can allow up to several times increase in the effective positioning resolution of the actuators driving the kinematic coupling mechanism. However, the magnitude of the leverage is not homogeneous over the entire working envelope of the mechanism. Furthermore, in some areas, the magnitude of the leverage is shown to be very sensitive to perturbations in the design parameters. This paper provides a discussion of the parameter design analysis for the proposed system using a methodology based on design of experiments and nonlinear mathematical programming. Using an indicator developed for this purpose, a response surface for the mechanical advantage is obtained and optimal design areas are identified. More importantly, this analysis proves to be flexible enough in searching for the set of parameters that would achieve any particular target on the level of performance, while presenting the least sensitivity to manufacturing noise. This allows for manufacture of variations of the proposed mechanism within feasible manufacturing tolerances and costs. A case study is also presented as an illustration of one real application in manufacturing design. Additionally, potential areas of implementation, such as precision assembly and rapid prototyping, have been identified.}, number={4}, journal={JOURNAL OF MANUFACTURING SYSTEMS}, author={Taylor, JB and Carrano, AL and Fathi, Y}, year={2000}, pages={229–238} } @article{taylor_carrano_lemaster_1999, title={Quantification of process parameters in a wood sanding operation}, volume={49}, number={5}, journal={Forest Products Journal}, author={Taylor, J.
