Manufacturing Process Verification

The manufacturing process covers all the steps and phases to create a part from raw material to finished product. It starts with melting and solidification, then product forming, machining, and joining, followed by heat treatment

This book sets itself apart by covering seven key subjects geometric measurement, part evaluation, materials identification, manufacturing process verification, data analysis, system compatibility, and intelligent property protection. Helpful in making new compatible products that are cheaper than others on the market, the author provides the tools to uncover or clarify features of commercial products that were previously unknown, misunderstood, or not used in the most effective way.

The inspection should cover the evaluation and assessment of the documentation, premises, equipment, utilities and materials. It should also cover verification of data and documentation such as results, batch records, compliance with SOP and information submitted on the manufacturing method, equipment and aspects including (but not limited to) validation of the manufacturing process, validation of utilities and support systems, and validation of equipment. 

For function verification and optimization, a functional product example is required. The application of production series materids is not always necessary for this purpose. Functional prototypes should, however, display similar material strength characteristics. On the other hand, technical prototypes should be produced using the respective production series materials and, whenever possible, intended production fine equipment. The latter serve for purposes such as customer acceptance checks and the verification of manufacturing processes. 

FTA extracts a lot of bottom elements that seem to be latent in design process, manufacturing process, management process and so on. We examined every identified bottom elements and their verification process. An example of summary table is shown in Table-1. 

Section 3.8.2 System/Cost Effectiveness Analyses. Describes the implementation of system and cost effectiveness analyses to support the development of fife cycle balanced products and processes and to support risk management. Describes the MOEs, how they interrelate, and criteria for the selection of measures of performance (MOPs) to support the evolving definition and verification of the system. Includes description of the overall approach for system/cost-effectiveness analysis as well as manufacturing analysis verification analysis distribution analysis operational analysis hiunan engineering, manpower, personnel, and training analysis usability analysis supportability analysis safety, health hazards, and environmental analysis and life cycle cost analysis. Describes how analytical results will be integrated. 

P(l) The properties of the materials and their suitability, the dimensions of the finished components and the equipment used shall be subjected to a regular system of verification during the manufacturing process. 

Different verification systems are appropriate for different manufacturing processes. For a continuous process, the main checks are on the supply of materials and the operation of the machinery such that the product is of a uniform quality. There is only a limited workmanship aspect once the process has been set up and is running, Conversely for single products there is likely to be a large element of workmanship and hence control will be concentrated in this area. 

Process verification testing is often called screening. Screening involves 100% auditing of all manufactured products to detect or precipitate defects. The aim is to preempt potential quality problems before they reach the field. In principle, this should not be required for a well-controlled process. When uncertainties are Hkely in process controls, however, screening is often used as a safety net. 

Aerospace has continued to provide many engineering, design, and safety services to the Air Force for more than 40 years. One of its chief functions is to perform launch verification and readiness assessments for all Air Force space launches. Aerospace s launch verification procedure is veiy broad, beginning with analysis of launch system design. Aerospace independently tests physical components and software, checks manufacturing processes, and verifies correct assembly of the launch vehicle. Finally, Aerospace delivers a formal launch verification letter to the Air Force s Space and Missile Systems Center, monitors the launch, and analyzes launch and post-launch data (Tomei, 2003). All of the functions are redundant in the sense that Air Force and contractor personnel also perform most of the same functions. Aerospace s launch verification serves as an independent, objective assessment of launch safety that the Air Force uses in conjunction with its own analyses in making launch decisions. 

Investigation into the vial manufacturing process was initiated to determine the root cause of the contamination. The vials are most commonly glass, since this provides an inert contact surface and transparency for inspection and dose verification. The vials must be sealed, and at one end a piston must be provided while at the opposite end a septum is fitted to allow puncture by the needle inside the syringe barrel. The elastomeric components of both are shown in Figure 10-1 and Figure 10-2. An aluminum ferrule that is crimped to form a seal after the vial is filled surrounds the diaphragm.
