Definitions

  • SUBSTITUTE SHEET greatly improve the use of machining processes to turn precision finishes and diameters in normal production processes, and facilitate finishing and grooving, using cutting tools, as opposed to grinding in hardened materials.
  • FIGURE 1 A first figure.
  • the turret will have 8-10 tool positions to allow roughing and finishing tools to be put in or spare tools so that one doesn't have to be set up each time, but a group, for example, can be set up during down times, and simply indexed in when a tool breaks.
  • the problem of tool set up will be addressed elsewhere, but it basically involves putting the tool tip at the correct location known to the machine, whether it checked after putting in and the machine is corrected, or its put in to a correct location. This particular operation is made much simpler by use of the invention herein.
  • the air nozzle (or suction) 160 is utilized to deflect or catch flying chips, debris, etc. and where use coolant, that is being spun up by the rotation of the workpiece in those cases where the workpiece is not already cleaned sufficiently. It also serves to clear off the workpiece surface. If the workpiece was rotating in the other direction, the nozzle would be on the other side.
  • the invention is still operable, even during cutting, with relatively small amounts of coolant directed, as with coolant direction micro nozzle 165, directly at the tool tip.
  • coolant direction micro nozzle 165 typically such a nozzle would be optimally built right into the tool itself, and it is the feature of the invention to be able to controllably turn this coolant off, if desirable to enhance the ability to get a good reading of the sensor unit, noting that otherwise coolant can cause erroneous readings due build up of film on the surface to the lumps of film on the surface, or can cause the windows of the system to become distorted optically.
  • air blows such as 170 are also utilized where needed to clear the window. Fortunately for dry cutting, little or no requirement for such air usage has been required.
  • the system is capable of running approximately 10 readings/sec maximum. This is a good result, but is short of the 30 frames per second performance of typical RS170 solid state cameras.
  • a real time edge processor such as 190, is being developed, which can feed all edge data at frame rates; i.e. 30 HZ, into a parallel acquisition board of the computer. It will then not force the PC's own computer to find the edges (and to disregard any contamination, etc. thereon) , but only use it to do the corrections to the calibration tables, etc. It should be noted that the contamination rejection on the part surface, is desirably performed using methods described in Ref .
  • the computer 150 also includes optional processing, either within the main computer or within specialized "inference” cards 195, which constitutes an “inference engine”. This inference capability is used to compare sensor readings taken by the sensors of the machine, and compare the data against rules, which can be used to govern the actions of the machine.
  • the axis command while in motion would fire a pulse to strobe the light source with say a few nanosecond pulse (eg from a diode laser, which would freeze the data on the array, which could be read out later in sync with the strobe pulse to determine following error.
  • a pulse to strobe the light source with say a few nanosecond pulse (eg from a diode laser, which would freeze the data on the array, which could be read out later in sync with the strobe pulse to determine following error.
  • the light box 470 may be desirable to place a tilted window in front of this light source to allow dirt and other things to fall or slide off it.
  • a tilted window in front of this light source to allow dirt and other things to fall or slide off it.
  • slant bed lathes such as typically shown in Figure 5c
  • such a light source would be naturally tilted anyway with respect to the horizontal.
  • the lighting is not overly sensitive given the image processing capabilities today, or edge extraction, and that only great amounts of residual dirt on this window can cause problems. The maintenance procedure of once per shift, during dry cutting operations, is sufficient generally to keep this clean enough for operation.
  • air or suction is optionally employed herein as well, located in this case on the upper turret, to blow any residual contamination, that does not go downward, after cutting away from the part surface being measured, as well as the sensor
  • This computer has within it a data base obtained from measuring of the sensors of the machine(s), and process models containing control algorithms. It also can contain a machinability data base for accessing cutting data for materials and tools used, and a part data base obtained from a CAD or other design data source, for the various parts to be produced by the machines.
  • the machine is used to take the tool over to a measurement position, as has been shown above, and is independent of the measurement of the part.
  • the camera sensor is mounted actually on the tool holder itself.
  • a TV camera based sensor 890 including optics and imaging chip, such as an Elmo Brand EM 102BW is used to image the tool edge 891, when illuminated by light from an external or retroreflective mirror source, such as shown above.
  • the prediction of problems due to any sort of oversize stock ahead of the cutter can be made, and one can make an ideal depth of cut, without knowing anything at all about the part a priori, or the position of the machine by direct measurement of the locations of the surfaces, and then providing signals to the machine to move the tool in such a manner as to cause the depth of cut of a certain size to occur. Then if desired, one can inspect the surface cut to make sure that it is correct.
  • depth of cut information is mainly valuable for determining how many passes it may take to remove the material to get to the correct size, for a given combination of machine, tools and rough part, for any given combination of machine settings.
  • SUBSTITUTE SHEET of transducers based on analysis of actual results on the tool or part gathered by reliable sensors is a major feature of the invention.
  • Non contact sensors are preferably electro-optical for part dimension, but can be capacitive, infrared, ultrasonic, and acoustic emission or ultrasonic for dimension, or finish or internal defects.

Abstract

L'invention concerne essentiellement des améliorations apportées à des tours à commande numérique, ainsi que des procédés associés d'utilisation de ceux-ci. Un tour (11) à tourelle à commande numérique, connu dans l'art, est équipé de détecteurs (25) situés dans la tourelle (20). Ces capteurs sont équipés pour mesurer le diamètre ou les rayons équivalents de la pièce, la longueur, le finissage de la surface, et pour déterminer les forces de coupe. L'invention comprend l'ensemble de tous ces capteurs associés, afin d'améliorer l'usinage, la qualité de la pièce, ainsi que le prolongement du temps utilisable, et le rendement de l'usinage. Sont également illustrés l'étalonnage des capteurs et de la machine ainsi que l'affichage des capteurs, et les détails relatifs à un mode de réalisation de détection d'outil.
