The Updated Scope of Machines

Our journal Machines (https://www.mdpi.com/journal/machines) has been up and running for a few years now, publishing thought-provoking, ground-breaking research that covers the vast field encompassed by the concept of ‘machinery and engineering’. Now, the time has come to contemplate and look back at previous publications and consider whether the subjects listed in the scope of the journal are still appropriate and up-to-date. Considering the published papers and the developments in the various research fields, we have concluded that the subjects mentioned in the scope are largely appropriate and up-to-date. However, some fine adjustments and extensions can be made.

The basic scope is considered appropriate, but the listed topics have been updated as indicated in

Table 1. Present scope and the updated version.

Present Scope	Updated Scope
applications of automation systems and control engineering electronic engineering mechanical engineering computer engineering mechatronics robotics industrial design human–machine-interfaces mechanical systems, machines and related components history of technology and industrial revolution turbo machinery machine diagnostics and prognostics (condition monitoring) machine design	machines design and theory machines testing and maintenance electromechanical energy conversion systems electrical machines and drives condition monitoring and diagnostics automation and control electromechatronics mechatronics and intelligent machines advanced manufacturing vehicle engineering turbomachinery micro/nano electromechanical systems friction and tribology

With this update, we want to encourage more submissions in the fields mentioned and continue the progress of the journal in the right direction.
