Abstract
The invention relates to a method for controlling an automated orbital sander, in which method an electrically powered orbital sander is moved around automatically, at constant pressure, over the surface of an object, along at least one predefined sanding path so as to perform sanding, characterized in that the instantaneous power consumed by the sander along the sanding path is measured and in that the measurement thus taken is processed in order to deduce therefrom information regarding the level of abrasion along said path and/or to detect any sanding incident that has occurred along the latter.
Claims8
A method for controlling automated orbital sanding, wherein an electrically-powered orbital sander is moved in an automated way, at constant pressure, at the surface of an object, along at least one predefined sanding trajectory in order to achieve the sanding thereof,
- wherein the instantaneous consumed power of the sander is measured at different points along the sanding trajectory and in that the thereby conducted measurement is treated so as (i) to infer therefrom a piece of information on the abrasiveness of the object at each of the different measured points along said trajectory, (ii) to detect a possible sanding incident along the latter, or both, and
- wherein a colorimetric mapping of the instantaneous consumed power, the inferred abrasiveness, or both, at the different points along the sanding trajectory is displayed or edited, said mapping associating an instantaneous consumed power of the sander with a given position of the sanding trajectory.
A system for controlling an automated orbital sanding achieved by means of an electrically-powered orbital sander moved in an automated way, at constant pressure, at the surface of an object, along at least one predefined sanding trajectory in order to achieve sanding thereof, wherein it includes a device for measuring the instantaneous consumed power of the sander at different points along the sanding trajectory and a monitoring controller adapted for receiving the thereby measured instantaneous power and for treating the thereby achieved measurement in order to (i) infer therefrom a piece of information on the abrasiveness along said trajectory, (ii) detect a possible sanding incident along the latter, or both, said system including means to display or edit a colorimetric mapping of the instantaneous consumed power, the inferred abrasiveness, or both, as measured at different points along the sanding trajectory, said mapping associating an instantaneous consumed power of the sander with a given position of the sanding trajectory.
