APPLICATION OF SINGLE MINUTE EXCHANGE OF DIE ON MASS PRODUCTION COMPANY
(Military Technical College, 2018) A. Salah, S.; Sobhi, N.
Lean manufacturing philosophy is continually strive to eliminate the nun-value added activities, minimize the delivery cycle time and improve the quality of products. Most manufacturing companies adopt lean in order to meet customer expectations and become more competitive in the market. Implementation of Lean enterprise is an efficient and effective way to reduce the cost of the enterprise without incurring high capital expenditures. SMED is a popular lean tool used for dramatically reducing the set-up time for the machine, which is a set of techniques enabling for the replacement of tooling or set a production line in less time than 10 minutes. This paper focuses on implementing SMED methodology in a mass production company for food industries in order to reduce changeover time. The objectives of this paper are decreasing the setup times of the production line to enable the production flexibility and increase the maneuverability between different products according to customer needs. This paper monitoring carefully all production processes to identify all wasted time between processes and find ways to eliminate or decrease it. The achieved results indicate that implementation of SMED in the company has a significant impact on decreasing the setup times and increasing the total productivity and the net profit. The changeover time reduced by 25%, and the OEE increased from 48% to 70%, also, the sales opportunities increased by 465,600 EGP per year.
DEVELOPMENT OF LEAN CULTURE ASSESSMENT FOR LEAN MANUFACTURING IMPLEMENTATION
(Military Technical College, 2014) A. Salah, S.; Sobhi, N.; Ali, N.
Many companies are looking at lean manufacturing for helping them to remain competitive; Lean manufacturing is however more than just a set of tools and techniques as it also requires a change in the organizational culture of the company involved to be a lean culture. The relationship between an organization’s culture and its ability to implement lean six sigma technique is a long-term effort. As a first step, the purpose of this paper is to offer the results of a survey conducted to measure the lean cultures criteria in the manufacturing company which is conducive for successful implementation of lean six sigma methodologies. The method used for this paper study was the questionnaire method using a lean culture assessment questionnaire that has been designed by the researcher that was aligned to the important principles based on Toyota Way model. This study indicates that the existing organizational culture of radiator Production Company is relatively conducive to the implementation of lean principles within the company.
Investigation of critical lean culture criteria frame work for lean transformation
(Military Technical College, 2014) A. Salah, S.; Sobhi, N.; Ali, N.
ABSTRACTMany manufacturing companies when implementing lean manufacturing, they onlyemphasize on lean tools and techniques. They ignored the human factor or morespecific they failed to build the right culture. Hence, these companies could notobtain the full benefits of lean manufacturing implementation, and in fact, they arehaving difficulties sustaining the success attained. This paper provides a theoreticallean culture criteria framework for implementation of lean manufacturing. Thisframework builds on the literature review that involves major sources of leanmanufacturing community and also based on Toyota way culture. This studyinvestigates how the lean culture influences the implementation of lean system in allorganizations. The study further explains how an organization can benefit fromassessment of their culture by adopting lean culture framework. It is found from theliterature review that a number of factors need to be taken into account in order toimplement a successful lean system. The framework would enable the organizationsto assess their internal culture before implementing lean methodology.
AN INVESTIGATION OF NORMAL PERFORATION OF A SMALL CALIBER PROJECTILE INTO METAL/COMPOSITE LIGHTWEIGHT TARGETS
(The Military Technical College, 2003) M. Riad, A.; I. Fayed, A.; A. Salah, S.
In this paper, an experimental program has been conducted to study the normal perforation of a small caliber projectile into metal/composite targets. This program is concerned with the determination of ballistic resistance for a set of targets, consisting of kevlar/epoxy composite with different thicknesses faced by 1.6 mm-thick duralumin plates. The used textiles (kevlar129) for manufacturing the composites have a new weave shape (3D weaver"'), which permits the epoxy resin to diffuse through it. In addition, tensile tests of manufactured composite specimens are performed to determine their mechanical properties. An analytical model has been presented to describe the penetration process of metal/composite lightweight targets and to evaluate their ballistic resistance against small caliber projectiles. The present model consists of two parts; the first is based on energy balance principle for modeling the projectile penetration into a thin metallic plate failed by petalling [1], whereas the second uses the circumferential strain as a failure criterion for modeling the projectile penetration into a composite target [2]. The main equations representing analytical model are presented. These equations are arranged and compiled into a computer program. The input data to run the program are easily determined. Representative samples of the obtained results are presented with relevant analyses and discussions. The ballistic measurements of the experimental program are compared with the model predictions; good agreement is generally obtained. In addition, new target configurations are constructed and tested; these targets have the capability for defeating the projectile with the highest impact velocity used.
INVESTIGATION THE CRITICAL SUCCESS FACTORS OF TQM CRITERIA IN THE INDUSTRIAL ORGANIZATIONS
(Military Technical College, 2016) Sobhi, N.; A. Salah, S.; Magdy, E.
ABSTRACTTotal quality management is a philosophy of management for continuously improvingthe quality of products and processes. The quality of products and processes is theresponsibility of everyone who is involved with the development or use of theproducts or services.TQM implementation provides people with opportunities to learn and to developthemselves. TQM enables all employees to participate in the continuousimprovement process to improve the organizational performance and assurecustomer's satisfaction. A company that is able to assess and understand its TQMsuccess factors can focus on improving its performance. This paper investigates thecritical success factors of TQM criteria in the industrial organizations, which hadachieved the certificate of the quality management system (ISO 9001). This paperused a questionnaire survey method to assess the actual level of implementation ofthe TQM systems in the organizations. The results of the data analysis identifiedeight factors that affect companies’ performance; leadership; customer focus;involvement of people; process approach; continuous improvement; supplierrelationship; decision-making and communication. The results indicate that thesuccessful implementation of total quality criteria in the industrial organizations leadsto a significant increasing in the performance and business environment.
PERFORATION OF A SMALL CALIBER PROJECTILE INTO TEXTILE/EPDXY COMPOSITE TARGETS
(Military Technical College, 2003) I. Fayed, A.; M. Riad, A.; A. Salah, S.
An experimental program has been conducted to study the normal perforation of a small caliber projectile into textile/epoxy composite targets. This program is concerned with the determination of ballistic resistance for a set of targets, consisting of kevlar/epoxy and S-2 glass/epoxy composites with different thicknesses. The used textiles (kevlar-129 and S-2 glass) for manufacturing the composites have a new weave shape (3D weaveTM), which permits the epoxy resin to diffuse through it. In addition, tensile tests of manufactured composite specimens are performed to determine their mechanical properties. The analytical model developed by Taylor and Vinson [1] is adopted herein to describe the penetration of a small caliber projectile into a textile/epoxy composite target. The selected model uses the circumferential strain as a failure criterion for a composite target. The main assumptions and equations representing the analytical model are presented. These equations are arranged and compiled into a computer program. The input data to run the program are easily determined. The ballistic measurements of the experimental program are compared with the model predictions; good agreement is generally obtained. The obtained results show that the tested composites with different thicknesses have a limited ballistic resistance against the used projectile. Moreover, other types of epoxies are recommended be used for manufacturing the composites and the effect of epoxy type as well as the delamination between composite layers on their ballistic resistance must be considered.
