Abstract (en)
[origin: WO2016062491A1] A device (2) for determining a penetration depth in a drilled hole which is drilled into a workpiece (W) from a workpiece surface (WO) with a drill of a drilling machine (1). The device contains at least one light source (9) for projecting a light field (17), for example onto a workpiece (W) to be processed by the drilling machine (1). The light source (9) is positioned with respect to the drilling machine (1) in such a way that a centre axis (L) of the light source (9) runs at an angle (a) with respect to a central axis (L) of the drilling machine (1), and at least a first blocking element (12a, 12b, 12c) for partially covering the light source (9) is provided, said blocking element (12a, 12b, 12c) generating a scaling device (19) on the light field (17).
