  • TITLE "MACHINING MECHATRONIC SYSTEM AND KIT FOR DRIVING THE MECHATRONIC SYSTEM"
  • the present invention refers to the field of the industrial machines, such as in a non-limiting example the electronic driven machine tools.
  • machining systems using remote controlled industrial machines have modes of use which are often too complex and such to slow down the manufacturing process.
  • Such complexity mainly consists in the necessity of insuring the access to the remote control devices, for example, to a limited number of persons (each having possibly a specific authorization) and/or as an alternative to the main commands (for example the main operator panel) .
  • the complexity of the known systems resides also in the necessity that the remote control devices should be small and light, consequently the space available for displaying the required information and/or interacting with the machine is very limited. This also means that for displaying the correct group of information and commands ("interface") enabling the operator to interact with the machine to perform a specific functionality, it is necessary to navigate through several menus and sub-menus.
  • Such interface could be a group of graphical, textual, multimedial information (for example video or sound information) enabling the operator to interact with the machine when he/she must perform a specific functionality (control, servicing, monitoring) . Therefore, the activation on the control terminal of such interfaces can require a time-consuming and complex navigation through said "menus” which in turn requires time, leads the operator to the conditions of making a mistake, and, above all, does not enable the operator to concentrate (for example by his/her eyes) on what the machine is doing.
  • an object of the present invention consists of submitting machining systems which at least partially solve the abovementioned problems, by ensuring a faster and simpler interaction between the operator/operators and machine.
