Chemical contamination to operator machine or product. If component is not sensitive to the characteristics listed Ap . A component is said to be thin if one of its major dimensions is mm thick. Includes mechanical and air assisted mechanisms. Figure Handling process risk hp this expertise should be used to augment the analysis. Because the assembly variability knowledge collated is a mixture of quantitative and qualitative data validation of the indices used in the charts is more difficult than the manufacturing variability risks analysis. Experts from the assembly industry were therefore used in their final assessment and allocation. However despite the fact that the validation of the assembly capability measures are difficult to determine empirically they are found to be of great benefit when comparing and evaluating a number of design principles. 66 Designing capable components and assemblies START Key to values AUTOMATED MANUAL D Is there reliance on the process to - I achieve accurate positioning 2 No Yes Operator control Positional tolerance using automation Zonly xm 7 c Part placing process
