Table 2 gives the parameters used for shot peening the dog bone samples. Shot peening was done using a Westward blast cabinet equipment with a pressure regulator. To produce consistent results, the jig in Fig. 9 was used to secure the sample. Fig. 8 Pseduo-Almen strip deflection after shot peening. ABS 1.75 mm filament X Y Z

oxygen fuel (HVOF) sprayed bond coats are under investigation as a cost-efficient alternative (Toma, 1999). Plasma spraying is a complex process which depends on a large number of process variables (Fauchais, 2001). This complexity makes a control of the process and hence, of the microstructure of the coating, difficult. However, the potential of

Statistical Process Control (SPC) applies statistical methods to monitor and control a process to operate at full potential. Statistical process control is a collection of tools that when used together can result in process stability and variance reduction. Control charts are used in SPC for measuring the variation in the process and that can be

Although simple to use, they are very powerful for process analysis. In Part 3 of Statistical Methods for Process Improvement we will learn about using several types of control charts and how to interpret what a process is 'telling' us. However, before considering any specific chart, let's examine control charts in general. Process Control .

The stainless steel substrates which had been coated with the NiCr-Cr 3C 2 powder to a thickness of *400 lm were heat treated in laboratory air at 700 and 800 C for up to 16 days. In these experiments, the exposed coating surface was in the as-sprayed condition, i.e. no prior surface grinding or polishing had been undertaken. The samples

When we learned how to use machines, electronics, and comput-ers to replace the human function, the term automatic control came into use. 2.1 Process-Control .

The process is then said to be under statistical control. If a process is unstable, that is because unusual factors are operating on the process. These factors, known as special causes, result in the process being out of statistical control. Shewhart recognised that we make mistakes at times, in that we take action when we should not do so.
