The advancement of forging technologies and processes has enabled the increased use of forged products to meet the demanding requirements of strength, durability, and reliability. While forgings are commonly used in aerospace manufacturing, the ability to make use of precision forging processes and techniques is critical when manufacturing gas turbine components. Realizing the benefits of accuracy and quality that precision forging brings to product manufacturing requires those involved with design and manufacturing have an understanding of industry accepted technology and processes.
Training / Education Classroom Seminars
One of the main advantages of the precision forging process is the reduction in material consumption due to the achievement of close tolerances and the reduction of machining requirements to meet final component specifications. However, to achieve these results comes at a cost. One of the primary issues with precision forgingis the reduction in life of the tools used in the forming process. Manufacturers can mitigate some of these concerns by better understanding how tools can be designed specifically for the precision forging process and how personnel can effectively apply precision forging techniques.

The rapidly evolving demand for cost reductions and shrinking budgets makes the application and use of automated processes within the aerospace and space industries a necessity. While some view aerospace automation as the solution to reducing costs, others view automation technologies and processes as something that should be avoided when possible. Misunderstandings and assumptions about these complex systems can result in the improper selection and application of these systems, often leading to undesirable interactions with other elements of the assembly process and potentially, project failure.

Additive manufacturing (AM), with origins in the 1980s, has only more recently emerged as a manufacturing process of choice for functional part production, adding to the suite of choices a designer has available when designing a part for manufacturing. Like other traditional processes like casting and machining, AM has its set of constraints. An added layer of complexity comes from the fact that there are several different AM processes, and some of the design constraints are process-specific.

This paper presents an enhanced Bayesian based model validation method together with probabilistic principal component analysis (PPCA). The PPCA is employed to address multivariate correlation and to reduce the dimensionality of the multivariate functional responses. The Bayesian hypothesis testing is used to quantitatively assess the quality of a multivariate dynamic system. Unlike the previous approach, the differences between test and CAE results are used for dimension reduction though PPCA and then to assess the model validity. In addition, physics-based thresholds are defined and transformed to the PPCA space for Bayesian hypothesis testing. This new approach resolves some critical drawbacks of the previous method and provides desirable properties of a validation method, e.g., symmetry. A dynamic system with multiple functional responses is used to demonstrate this new approach.

Mathematical modeling is widely used throughout any scientific industry when trying to predict the behavior of dynamic systems. Oftentimes it is desirable that these models be simple and efficient, while still delivering accurate data. This paper builds and examines an energy-based (bond graph) model of an automotive fuel delivery system and suggests which elements are required to produce a Proper Model. The Model Order Reduction Algorithm (MORA) provides a mechanism to quantitatively rank each element in the model and determine its contribution to the system dynamics. Utilizing this approach, a model is developed that retains 98% of the complete system energy from 12 of the most active of 25 elements. This model requires 46.6% less simulation time while continuing to provide an adequate prediction of the system response.

Magnesium alloys are the lightest structural metal and recently attention has been focused on using them for structural automotive components. Fatigue and durability studies are essential in the design of these load-bearing components. In 2006, a large multinational research effort, Magnesium Front End Research & Development (MFERD), was launched involving researchers from Canada, China and the US. The MFERD project is intended to investigate the applicability of Mg alloys as lightweight materials for automotive body structures. The participating institutions in fatigue and durability studies were the University of Waterloo and Ryerson University from Canada, Institute of Metal Research (IMR) from China, and Mississippi State University, Westmorland, General Motors Corporation, Ford Motor Company and Chrysler Group LLC from the United States.

Magnesium alloy extrusions offer potentially more mass saving compared to magnesium castings. One of the tasks in the United States Automotive Materials Partnership (USAMP) ?Magnesium Front End Research and Development? (MFERD) project is to evaluate magnesium extrusion alloys AM30, AZ31 and AZ61 for automotive body applications. Solid and hollow sections were made by lowcost direct extrusion process. Mechanical properties in tension and compression were tested in extrusion, transverse and 45 degree directions. The tensile properties of the extrusion alloys in the extrusion direction are generally higher than those of conventional die cast alloys. However, significant tension-compression asymmetry and plastic anisotropy need to be understood and captured in the component design.

Companies are often faced with periods of fluctuating product demand that can make it difficult to maximize the usage of their capacity and resources. This makes it challenging to realize potential profit and can even have detrimental effects on the bottom line. Developing flexibility strategies to react to fluctuations in demand allows a manufacturer to dynamically adjust capacity and resources to keep costs under control. This project was pursued at a diesel engine manufacturer for two older product lines experiencing consistently declining volumes. The volumes were declining due to this company releasing newer products in the market, and the current economic downturn. There was also an expectation to eventually phase out these two engines after approximately five years. A project team was formed to address these challenges starting with defining the project scope, setting up the team and a cross-functional project structure, and developing work packages with a master timeline.

OEE or Overall Equipment Effectiveness is the metric that ties machine availability, performance and part quality together. OEE is calculated using the formula, OEE = Machine Availability x Machine Performance x Quality of parts produced by the machine. The ideal value for plant OEE is 100% which means all machines have zero downtime, full availability and are not making any non conforming parts. Studies show that average OEE in the manufacturing industry is about 60% whereas world class OEE is 85%. Most manufacturers have room for improving their OEE. In order to improve OEE, this metric needs to be monitored for all machines or equipment in the plant. And there is nothing simpler than a dashboard to monitor OEE for plant equipment.

Organizations spend millions of dollars on analytical and simulation inventory models to optimize inventory across the supply chain. However, these methods are expensive, difficult to implement and fail to capture all the requirements for defining inventory levels across supply chain. The effect of planned and unplanned equipment downtime, a key factor, is not properly utilized in these models. Many methods use standard statistical distributions, which do not fully capture downtime characteristics of an operation. This may lead to inaccurate computation of inventory sizes. The purpose of this paper is to communicate a new analytical approach of defining inventory levels which is robust enough to consider non-normal distributions associated with equipment downtime. The proposed method is easy to use, less time consuming and can be adapted quickly with changing operational dynamics. The method is based on utilizing equipment performance data to scientifically compute inventory levels.

Implementing the lean principles and tools in manufacturing has been successful in many companies. This success has led to different implementations, of these principles, in other organizational activities such as design and management. While these implementations can produce some improvements, the segmentation of the product development processes in most company limits the potential for achieving the desired goals and in some cases the success of the implementation process itself. In other words, full success of lean principles implementation cannot be achieved when applied to isolated segments of the product development process. This paper addresses lean design, in the context of a fully integrated product realization process. The paper discusses the integrated nature of any product realization process and its flow from concept to production.

Significant research has been conducted with the goal of obtaining thin walled ductile iron for use in lighter weight designs. A review is made of the past efforts to achieve thin walled ductile iron. Most past efforts resorted to costly processes or non-standard production practices. Lost Foam Casting (LFC) is an alternate foundry process which used in conjunction with standard melt shop practices results in a massive carbide free structure when used with thin section size. Chemistry, hardness tests, microstructures, and design improvements of a case study are reviewed.

The process capability indices are widely used to measure the capability of the process to manufacture objects within the required tolerance. Fit quality is mainly dominated by the distribution of fit dimensions, i.e., a gap dimension. As the fit dimensions are very difficult to be measured in mass production, they are not to be considered as a direct inspection objective. The quality inspection and evaluation relative to fit quality are focused on whether the processes of assembly requirements are conformed with their specification limits respectively. Fit quality specification can be indicated by the process capability indices of mating parts. In this paper, the statistical-based process capability analysis method is presented to estimate ability of manufacturing process for considering of assembly requirements and fit quality in a mechanical assembly with asymmetric tolerances.

Failure modes of spot friction welds in cross-tension specimens of aluminum 6061-T6 sheets are first investigated based on experimental observations. Optical and scanning electron micrographs of the welds before and after failure under quasi-static and cyclic loading conditions are examined. Experimental results show that the failure modes of the welds under quasi-static and cyclic loading conditions are quite different. Under quasi-static loading conditions, the failure mainly starts from the necking of the upper sheet outside the weld. Under low-cycle loading conditions, the dominant fatigue cracks are the kinked cracks growing into the upper sheet from the crack tips; hence, the upper nugget pullout failure mode can be seen. Under high-cycle loading conditions, the dominant fatigue cracks are kinked cracks growing into the lower sheet from the crack tips; subsequently, the lower nugget pullout failure mode can be seen.

This paper proposes an alternative methodology to construct a dynamic failure model of spot welds under combined axial and shear loading conditions for auto-body crash analyses performing cross-tension tests and lap-shear tests which are substitution of pure-shear tests. To construct a failure model of a spot weld proposed by Song and Huh, failure tests of spot welds with an imposed angle to the weldment have to be carried out at an interval of 15° from 0° to 90°. In the general case, it was suggested that the β value of 1.45 from the results of the failure load of cross-tension tests and pure-shear tests can be used for constructing their failure model. However, the scheme is not practical because of difficulties in making pure-shear specimens with the same welding conditions of two-sheet spot weld because the pure-shear specimen is generally prepared with three-sheet spot weld.

The inspection of steel welds is a requirement in many safety critical applications, with X-rays offering an excellent visual aid in quality monitoring of such parts. In order to penetrate the steel and the weld, high energy X-rays are usually required though, depending on the material's thickness and the length of material the X-ray beams must traverse. The high beam energies can seriously degrade the X-ray detectors' life expectancy and image quality, so in order to ensure consistent image quality traditional X-ray film has been used, in spite of its drawbacks regarding the ecological impact of the chemical process and the significant efforts involved if archives of the welds must be maintained. This paper presents an alternative solution to the traditional photochemical archival approach using a custom X-ray detector developed specifically for the inspection of welded seams.

Being environmentally conscious in reducing CO2 output, is driving industries to be more efficient in using resources. Industries are also finding ways to reduce energy consumption for all aspects of manufacturing. The brake lining manufacturing process relies on electric power during the thermoset cure and post-cure of Phenol Novolac resin. Unreacted resin will complete its cure process during the ‘post-cure’ phase. The electric power consumed during the molding and post-cure process is significant compared to the total power consumed for the entire lining manufacturing process. By using Novolac Benzo-oxazine resin and utilizing high temperature short cycle molding, we could reduce power consumption. The finished Phenol Novolac brake lining will have the same performance as the phenol brake lining. A substantial reduction in electric power consumption is achieved with the new process.

In this paper, a new diesel particle filter material made from silicon carbide sintered in a liquid phase is presented. The sintering process allows for controlling of certain parameters that influence the extrusion process, the material properties and hence the filtering characteristics. Furthermore, using triangular channel geometry to build up a wall flow filter makes it possible to have a newly segmented geometry that leads to hexagonal shaped filter cartridges. A variety of on the market available wall flow filter materials are compared with data about material porosity, particle size distribution, strength, specific filtration surface as well other parameters influencing the filtration efficiency. The material characteristics gathered are analyzed and evaluated.
