Tools mechanical workshop

Several instruments and devices are certainly commercially available the need however for the availability of a precision mechanical workshop close to the laboratory must be underlined, since the construction of special apparatuses and components is often required, involving many machine tools (lathes, milling machines, presses, etc.), parts and different materials. See for instance remarks reported by Schnepf and Schnockel (2002). 

The main drawback to electrochemical machining lies in the need to design a tool (cathode) for each new job. Moreover the design process to obtain the correct current density distribution remains a skilled art rather than a science it is often necessary to test the tool and to modify it by trial and error. In addition the need to use large volumes of electrolyte solutions does not fit in well to a mechanical workshop. However carefully they are handled, they lead to corrosion in the environment. 

The introduction of weekly case study problems encouraged student engagement with the topics covered and promoted self-learning. As a result the workshop and tutorial sessions provided an enjoyable educational environmental where detailed discussion on the practical application of soil mechanics principles tool place, promoting learning for students, post-grad demonstrators and staff members alike. 

Table 35.5 Air consumption of pneumatic equipment Examp/e of ca/cu/af/on The following calculation is typical of a medium-sized engineering workshop including a foundry, where a high degree of mechanization is to be carried out by means of compressed air-driven machines and tools. Listed in the table are the tools and other pneumatic devices which are expected to be included in the installation at full production capacity. The use factor of the different tools is calculated in connection with production planning and thus it is possible to establish the average total air consumption.
