A Study Of The Manufacturing Costs Of Grille And Side Screens On John Deere Tractors, John M. Beierschmitt

Graduate Research Papers

The problem discussed in this paper was the development of a process for the manufacture of a new, low cost, quality grille screen that previously had been made on conventional tooling, and now can not be made with the conventional process or tooling. The research comparison in this paper was done to show the financial advantage of this type of tooling.

An Examination Of The Labor Time Of A Robot Weld Cell, Chris S. Conrad

Graduate Research Papers

The purpose of this study was to determine the labor time differential, if any, of a robot weld cell as compared to manual welding methods. Also, the variability of labor time differential between part numbers was to be examined.

The results of the study was intended to assist future investment decision makers in maximizing the return on capital expenditures. It was proposed that the labor time differential determined by this study be applied to the future labor and overhead rates in determining the return on investment for a robotic weld cell purchase. The variability of labor time differential between part …

An Investigation Of Cutting Tool Chatter Vibration In Machine Tools, Arneil Olson

Graduate Research Papers

The purpose of this study was to assemble and condense the research and background literature available on cutting tool chatter vibration. Another requirement was to translate the highly technical language of the researcher into a form readily understandable to shop floor personnel.

Support staff called upon to assist in the elimination of chatter problems have not been given the informational resources necessary to effectively deal with the phenomenon. This information should be gathered from university libraries and cutting tool experts and combined into one basic reference work.

If collecting the references were all that was required they could simply be …

An Investigation Into Manufacturing Quality Planning Concepts For New Manufactured Products With Recommendations For John Deere, Michael A. Henning

Graduate Research Papers

President Bush was quoted in 19 90 saying, "The improvement of quality in products and the improvement in services -these are national priorities as never before." (National, 19 9 0). Leadership through quality was also called the new competitive frontier by David Keams, Chief Executive Officer of Xerox Corporation (DeToro, 198 7) and 198 9 winner of the Malcolm Baldrige National Quality Award. For a manufacturing organization like Xerox a quality product is the result of many factors. Other corporations have come to the same realization of the importance of quality throughout their operations (Crosby, 19 9 1). He pointed …

Testing The Economic Order Quantity Model On Maintenance Inventory, Teresa J. K. Hall

Graduate Student Work

This pilot study seeks to determine the effect a non-traditional method of inventory control may have on industrial maintenance repair parts inventory. The application of mathematical models designed for production inventory to Maintenance, Repair and Operating (MRO) inventory has not been widely researched, although theorists and practitioners feel there is potential for some models. The Economic Order Quantity (EOQ) theory has proven to be effective in production inventory circles. This pilot study examined the effectiveness of the EOQ in terms of holding cost of the inventory and number of out-of-stock conditions versus the Weighted Moving Average method currently in use …

Osha Compliance By Small And Medium Business, Bill W. Trammell

Graduate Student Work

It is hypothesized that even though governmental rules, regulations, and policies along with ethical. social, and moral dictates within our communities now require, even demand, that businesses and industry provide their employees a healthful and safe working environment the opposite is often the case. There is a substantial number of employers, within the small to medium sized industrial manufacturers, whose chief executive officers: (1) fail to implement a safety program within their organization; (2) fail to provide more than token attention to employee safety and the intent of the OSHA regulations; (3) have no sincerity or intention to complying with …

An Assessment Of Just-In-Time Manufacturing, Ronald E. O'Meara

Graduate Research Papers

Manufacturing of materials into useable products has changed dramatically since the Industrial Revolution. The United States dominated the manufacturing arena until the early 1970s. After that period, efforts of global competitors in such areas as quality control and productivity, started to surpass the efforts made by the United Stated in these same areas. For the first time, U.S. manufacturers started sensing the pressure of competition. The United Stated is using its competitive advantage over other nations in the manufacturing segment. Part of this loss is a result of the way the U.S. manufacturers are conducting their business. A larger part …

An Experimental Cost Model For The Analysis Of Quality Cost In A Manufacturing Enterprise, Wallace Charles Carlson Jr.

Dissertations and Theses @ UNI

The intent of the study was to construct a quality cost model for manufacturing enterprises. A quality cost model provides a manufacturing enterprise with a cost structure which enables it to gauge and measure the efficiency and effectiveness of its management and processes. The quality cost model was specifically constructed to aid a manufacturing enterprise in establishing a quality cost system for its operations and activities and contains three distinct initial implementation or decision areas; the quality cost management decisions area, the quality cost system applications area, and the quality cost system utilization area.

The quality cost model was evaluated …

A Survey Of Material, Process, And Operator Requirements Of Midwestern United States Laser Job Shops, Eric Jaeckel

Graduate Research Papers

Managers of seven (7) midwestern United States laser job shops were interviewed to assess the material, process, and operator requirements of each particular shop. The seven shops were located in a six (6) state area including Illinois, Indiana, Iowa, Minnesota, Ohio, and Wisconsin,

It was found that mild steel and ceramic were the most common materials processed. Cutting, marking/scribing/etching, and drilling were the most common types of processing and gas lasers were six times more popular than solid state lasers. Operator training should include materials science, electronics, optics, and computer programming.

The Relative Importance Of Competencies Needed By Industrial Energy Managers From The Larger Manufacturers In Iowa, Timothy J. Eibes

Graduate Research Papers

The importance of identifying the competencies needed by energy managers is reflected in the seriousness of the energy problem and the impact it has on the industrial setting. The newness and ambiguity of EM, coupled with the increasing importance of the concept, add to the need for identifying the necessary competencies required in managing energy.

Ideally, once these competencies are identified, they should be the focus of those educational curriculums designed to produce energy managers. Currently there are only 25 post-high school institutions in the U.S. that have energy management curriculums (The College Blue Book, 1981). Less than half of …

The V-Process: An Innovative Foundry Technique, Thomas John Miller

Graduate Research Papers

The V-Process is an innovative foundry technique that is relatively unknown in the United States (Dreger, 1976, p. 63). The V-Process, known as vacuum sealed molding of unbonded sand, is a patented industrial foundry practice. Plastic film, unbonded sand, and vacuum are used to encapsulate the mold cavity.

Initially, the V-Process was used to produce intricate ornamental and- art castings. The V-Process has been used to produce castings of all sizes and shapes including castings having thin section curtain walls. Other castings include 2600 pound iron ore crusher mills and eight ton ship anchors. V-Process castings weigh as little as …
