Design and Manufacturing: Selected short answer questions from AMIE exams (Summer 2017 to Summer 2020)
Write briefly about mould wash. Mould wash: A coating applied in liquid form to walls of a mould cavity. What is adaptive control? Adaptive control: Adaptive control is a set of techniques that permit to adjust the value of control parameters in real-time, permitting to monitor controlled variables even if plant parameters are unknown or if they change. This control is a special kind of non-lineal control, and the process can be split into two timelines: rapid time (feedback loop) and slow time (variation of control parameters, which affects automation). What do you understand by the term machinability index? The machinability index is used to compare the machinability of different materials in the various cutting process. It is an attempt to quantify the relative machinability of a different material. What is tack weld? Tack Welding is basically a temporary weld performed during the Fitting of a part. This is done to ensure dimensional stability before actual Welding starts. Normally
