Abstract
Nowadays, the Large Scale Subtractive-Additive CNC Machines are used in rapid prototyping of superior parts for very sensitive systems used in aerospace and maritime technology. In this paper, design of a production platform of a Subtractive-Additive Machine is considered. The unit has workspace 2.5×6.5×0.5 meter with two heads that operate simultaneously. Each of the two processing heads will have 5 DOFs. While one is used for subtractive processing the other one does the additive processing and both work simultaneously capable of handling the products up to 500 Kg in weight. The Subtractive-Additive machine uses laser deposition welding with powder nozzle where the specimen thickness depends on size of powder, laser and nozzle geometry. In this study, many of the challenges of large scale systems, such as; large working area with escalated problems in design and operation, large weight handling of specimen, simultaneous operation of two heads/multi-heads, which may affect the response time and complication of production, effects on the precision of movement by using elevated magnetic bearing system, effects on the precision of the size on the end product, complexity of movement strategy, mutual effects of the two heads as integrated, vibration (mechanical as well as electrical EMI) as well as thermal effect and heat treatment during manufacturing has been considered and solutions to overcome such problems are suggested.
