An apparatus for dressing a grinding wheel

Abstract

An apparatus for dressing a grinding wheel mounted thereon by creating structures on the surface of a, in particular cylindrical, grinding surface of the grinding wheel The apparatus includes a dressing tool holder arranged for accommodating a dressing tool in a dressing position, a controllable actuator for adjusting the position of the tool holder within the apparatus in at least one direction, a grinding wheel support for rotatably supporting a grinding wheel to be dressed The apparatus further includes a mechanism for monitoring an individual structure, created by the dressing tool on the surface of the grinding wheel, and a mechanism for monitoring a circumferential position and/or the rotary speed of the grinding wheel, and a mechanism for controlling the actuator, adapted to control the actuator as a function of the monitored structure and the monitored circumferential position and/or rotary speed.

1 . An apparatus for dressing a grinding wheel mounted thereon by creating structures on the surface of a, in particular cylindrical, grinding surface of the grinding wheel, the apparatus comprising:
 a dressing tool holder arranged for accommodating a dressing tool in a dressing position,   a controllable actuator for adjusting the position of the tool holder ( 6 ) within the apparatus in at least one direction,   a grinding wheel support for rotatably supporting a grinding wheel to be dressed,   the apparatus further includes:   means for monitoring an individual structure, created by the dressing tool on the surface of the grinding wheel, and   means for monitoring a circumferential position and/or a rotary speed of the grinding wheel, and   means for controlling the actuator, adapted to control the actuator as a function of the monitored structure and the monitored circumferential position and/or rotary speed.   
     
     
         2 . An apparatus according to  claim 1 ,
 wherein the means for monitoring an individual structure are adapted to monitor the individual structure at the instant moment during creation of this respective structure.   
     
     
         3 . An apparatus according to  claim 1 ,
 wherein the means for monitoring the structure comprise an acoustic sensor for monitoring noise, which is generated during creating of the respective structure, the acoustic sensor is in particular attached to the dressing tool and/or the dressing tool holder.   
     
     
         4 . An apparatus according to  claim 1 ,
 further comprising:   an analyzing unit, adapted to reconstruct a structure created on the surface of the grinding wheel, based on the information provided by the means for monitoring an individual structure and the means for monitoring a circumferential position and the means for monitoring the rotary speed or circumferential position of the grinding wheel.   
     
     
         5 . An apparatus according  claim 1 ,
 wherein the apparatus comprises further means   adapted for comparing the monitored structure with a given predetermined structure and   means adapted for adjusting at least a control pulse for controlling the actuator of the dressing tool and/or a motor for driving the grinding wheel based on the result of the comparison.   
     
     
         6 . A method for controlling an apparatus for dressing a grinding wheel by creating structures onto a, in particular cylindrical, grinding surface of the grinding wheel, the apparatus comprising:
 a dressing tool holder arranged for accommodating a dressing tool in a dressing position,   a controllable actuator for adjusting the position of the tool holder within the apparatus in at least one direction,   a grinding wheel support for rotatably supporting a grinding wheel to be dressed,   the method comprising the following steps:   monitoring an individual structure created on the surface of the grinding wheel,   monitoring the circumferential position and/or the rotary speed of the grinding wheel, and   controlling the actuator of the dressing tool as a function of the monitored structure and the monitored circumferential position and/or rotary speed.   
     
     
         7 . The method according to  claim 6 ,
 wherein   the step of comparing the monitored structure with a predetermined structure,   wherein the step of controlling the actuator of the dressing tool is based on the result of this comparison.   
     
     
         8 . The method according to  claim 6 ,
 wherein the respective structure is monitored at the instant moment during creation of this respective structure.   
     
     
         9 . The method according to  claim 6 ,
