Definitions

  • the invention relates to a method, measuring device, finely adjustable tool holder with compensation device for process-integrated quality assurance, in particular for automatic condition monitoring of tool cutting edges in cutting NC machine tools.
  • the future factory sees itself as computer-controlled and flexibly automated. It has a continuous production process and is linked in terms of energy, materials and information technology.
  • a number of systems for tool breakage and wear monitoring are known, which are mainly used with good success during machining. However, they are only able to reliably record the actual happening at the cutting point under certain conditions.
  • Costly techniques of wear monitoring via force increase and force progression such as the learning process during the first idle times of a lot, can only take into account known known constant parameters. All variables that cannot be recorded often falsify the measurement result considerably.
  • a number of non-contact measuring devices which monitor the presence of a tool (twist drill) cutting edge in the transmitted light or reflex method.
  • the arrangement of the device in the work area is very susceptible to contamination due to contamination.
  • Tool length monitoring outside the work area e.g. on the tool magazine
  • Tool length monitoring outside the work area e.g. on the tool magazine
  • Machine-specific disturbance variables such as position spread and reversal span increase the measurement uncertainty.
  • Measuring-controlled, interchangeable precision turning tools are known, the cutting edge of which is automatically adjusted to a reference point on the inserted tool by means of an actuating unit in the work area.
  • Disadvantages are the measurement uncertainty, which results from the position of the reference point due to the clamping error and is transferred fully to the cutting edge, and the contamination of the coupling elements between the actuating unit and the fine bore cartridge in the working area.
  • Manufacturing systems have a tool presetting station with computer-guided tool presetting.
  • a device with contactless cutting edge scanning and digital position display, data transmission (correction values) to the machine control and a bar code printer for labeling the tools are part of the standard configuration.
  • the cutting edge must be corrected after two measurements on the cover with inductive measuring key.
  • the measurement, control and regulation system in the machine carries out both the setting in the ⁇ m range before the machining and the wear compensation after the machining, so that time-consuming and costly pre-setting is carried out.
  • - Position and workpiece measurement (control cut) can be omitted.
  • a significant advantage is the effective determination of wear through the micrometer-accurate measurement of all changes in the cutting edge - mainly flank and rake face wear as well as the cutting edge rounding.
  • the end of the service life is determined using 2 measured values:
  • the positioned cutting edge is guided by the x-axis in a 40 ⁇ m step through the laser beam and the contours are recorded in each position by a line camera. This creates a real picture of the cutting contour on the whole
  • the largest distance is decisive for the evaluation of the state of wear b (eg 0.35mm) measured horizontally from the edge of the insert, taking into account the material, cutting material, tool geometry and cutting conditions as well as the determined wear values, the optimum tool life is determined in a series of tests. Compensation devices on precision lathes and special units are known which automatically adjust non-exchangeable, finely adjustable tool holders via wedge, eccentric, slide, elastic deformation or tilt by the work spindle.
  • the disadvantage is that only firmly screwed tools can be controlled by the spindle.
  • Non-contact cutting edge detection by measuring the cutting edge position to a fixed reference edge on the work spindle. Random sources of error during the measurement are largely compensated for by the arrangement of the reference edge and by averaging a large number of measured values.
  • Systematic error sources are continuously corrected by the machine control system by recording machine and process states and comparing them with programs stored in the memory (analytically and empirically determined limit values, signal patterns and process models). In the event of a deviation, correction values are automatically entered.
  • Any quick-change tool holder can be used instead of a handle.
  • stepper motor-controlled compensation device for automatic setting lifting and wear compensation of all measurement-controlled tools.
  • the regulation takes place via the clamping elements of the steep ice (bolt, collet, pull rod, etc.) or a separate push rod through the work spindle and a controlled stop.

Abstract

Un procédé de contrôle automatique de l'état de l'usinage par des outils utilise une source de lumière pour contrôler toutes les fonctions, en procédant à une vérification du type de l'outil et du diamètre/longueur de l'arête coupante avant l'usinage/après l'échange d'outils et en vérifiant des cassures éventuelles de l'arête coupante et l'usure des outils de finissage après leur utilisation. Un appareil de mesure pour exécuter ce procédé fournit une mesure de référence par rapport à une arête de référence ayant des dimensions constantes par rapport à l'axe de la broche et une position verticalement modifiable selon le diamètre de la coupe en positionnant l'arête coupante sur un niveau à dimension zéro. Un porte-outil réglable avec précision pour exécuter le procédé ci-dessus comprend une barre de traction dont l'extrémité a la forme d'un boulon de tension pour serrer par traction l'outil auto-échangeable sur la colonne de ressorts et pour positionner/soulever l'arête coupante.
