2、. G. Campilho, R. M. Gouveia Abstract Machining is a manufacturing process widely used in the industry that directly impacts on technological development. The machining processes are carried out by machine tools, which may have manual, automatic or CNC operation. The automatic machines are suitable

3、for the production of parts with complex geometry and/or when it is necessary to produce parts on a large scale. In cases where there is a need to produce parts in large amounts, typically fully automatic CNC machines and processes are used, which increases the production capacity of the companies.

4、These machines require equipment capable of feeding the raw material to the inside of the machine tools. For that, throughout this work is developed the mechanical design of a bar feeder machine for CNC turning centres, that will operate with low cycle time and can be operated safely and in a quick

5、way by the operator. Keywords: Machining, Manufacturing process, CNC turning centres, CNC machines, Automatic bar feeding systems, Machine upgrade. 1. Introduction Machining is a subtractive manufacturing process widely used to obtain mechanical parts with very good surface finishing 1. It can assum

6、e different modes, depending on the geometry to be generated, shape complexity of the final part and surface quality required 2. A huge number of studies have been devoted to machining processes, since the optimization of machining parameters to the lifespan investigation of uncoated and coated tools with diverse materials and cutting conditions 3-6. Power consumption and other issues related to the sustainability have been also acutely investigated 7,8. Moreover, the lubricants have
