Surface mount component placement machines are being widely used in electronic manufacturing industry for automated placement of components on printed wire boards (PWBs). Their performance is determined by their board assembly time. Factors that determine this include the machine’s architecture and placement sequence algorithm, and component locations on the board. For a given machine and a boa...

Optimisation of feeder setup and component placement sequence are very important to the efficiency of surface mount placement machines. Much works have been conducted to solve this problem. However, the technological characteristics of the placement machine influences the nature of the planning problems to be solved and the formulation of the associated models. As a result, little consensus exi...

This study aims to design manufacturing system of a CNC Laser Engraver Machine. The starts from the laser module unit as input at stage 3-Axis Machine drive laser. There are several important components in production process machine, such Box Controller, Module unit, Z-Axis X-Axis and Y-Axis unit. Bill Material (BOM) is very ensure quantity specification materials, machines uses various types p...

Integral beta-barrel proteins are found in the outer membranes of mitochondria, chloroplasts, and Gram-negative bacteria. The machine that assembles these proteins contains an integral membrane protein, called YaeT in Escherichia coli, which has one or more polypeptide transport-associated (POTRA) domains. The crystal structure of a periplasmic fragment of YaeT reveals the POTRA domain fold and...

Highly optimised assembly lines are commonly used in various manufacturing domains, such as electronics, microchips, vehicles, electric appliances, etc. In the last decades manufacturers have installed software systems to control and optimise their shop floor processes. Machine Learning can enhance those systems by providing new insights derived from the previously captured data. This paper pro...
