  • Page 7: Introduction

    • Quality and type of material CINCINNATI machines are designed to be rugged and durable. However, improper adjustment or lack of maintenance can reduce the quality of parts produced on the machine. The quality of a laser-cut edge depends on the combination of a uniform laser beam of adequate power, properly focused on the workpiece with an adequate supply of the correct assist gas, traveling at a speed compatible with the material removal rate.

  • Page 21: Final Leveling

    FINAL LEVELING Final leveling should be done with a CINCINNATI INCORPORATED Service Representative present. The purpose of final leveling is to ensure that the gantry does not rotate about the X-axis as the gantry moves from end-to-end. Excessive rotation will cause laser beam misalignment during operation. Follow these steps for Final Leveling: 1.

  • Page 22: Electrical Connection

    The machine must be properly grounded in accordance with the National Electric Code NFPA 70, 2008 edition, article 250, sections 50 through 70. Place ground electrode per installation documents. Do not start the machine until Section 3 - SAFETY of this manual has been read thoroughly and a CINCINNATI INCORPORATED Service Representative is present.

  • Page 23: Safety

    SAFETY SAFETY IS EVERYONE’S JOB The CINCINNATI Laser System - Fiber Laser manufactured by CINCINNATI INCORPORATED has been designed to meet the highest order of reliability and ease of operator use. This system has been certified under Federal Regulations 21 CFR, subpart J, as a Class 4 Laser product as required by the Federal Radiation Control for Health and Safety Act of 1968.

  • Page 24: Safety Standards And Publications

    Radiation that lacks the energy to deform atoms is called “non-ionizing” radiation. This is the type used in CINCINNATI Laser System - Fiber Laser. The IPG or nLight product is a diode-pumped ytterbium fiber laser. The laser beam is emitted in a continuous wave (CW) at a fixed wavelength of 1.07 micrometers. This wavelength is invisible to the human eye.

  • Page 25: Laser Hazard Classification

    Laser safety specialists call these limits Maximum Permissible Exposures (MPE’s). The standards and publications listed below will be the most helpful to users of CINCINNATI Laser Systems: 1. ANSI B11.21 “American National Standard for Machines Using Lasers”.
  • Page 26 Since lasers are not classified on beam access during service, most Class I industrial lasers will consist of a higher class (high power) laser enclosed in a properly interlocked and labeled protective enclosure. In some cases, the enclosure may be a room (walk-in protective housing) which requires a means to prevent operation when operators are inside the room.

  • Page 27: Control Measures

    CONTROL MEASURES The CINCINNATI Laser System - Fiber Laser has been designed and manufactured using the highest engineering control measures practical. However, even these high standards have limitations. Laser safety requirements call for administrative and procedural controls to be incorporated in the use of lasers in order to minimize or eliminate the potential of personal injury during laser operation.

  • Page 28: Explanation Of Laser Radiation

    CINCINNATI Laser System - Fiber Laser uses solid-state diodes to generate the cutting beam. The actual laser- generating unit is located at the end of the CINCINNATI Laser System - Fiber Laser, and the beam is delivered to the cutting head through a fiber optic cable. See Figure 3-2.

  • Page 29: Hazards - Cincinnati Laser Systems - Fiber Laser

    EYE HAZARDS The beam of a CINCINNATI Laser System - Fiber Laser is a potential eye hazard. If the beam directly or indirectly hits the eye, there is a potential for injury to several different areas, depending upon which eye part absorbs the most radiant energy.

  • Page 30: Skin Hazards

    Unnecessary exposure of the skin to laser radiation should be avoided regardless of the level of radiant energy. The CINCINNATI Laser System - Fiber Laser has been tested and found to have no detectable x-ray emissions and related hazards.
  • Page 31 3446 ft. (1051 m) Figure 3-4 Uncontained Beam Hazard Distance The CINCINNATI Laser System - Fiber Laser’s design deals with beam exposure categories in various ways: • Intra-beam (Direct) Exposure occurs when an object is in the beam’s path. The fiber optic cable fully contains the beam to the fiber head.

  • Page 32: Associated Hazards

    8000 TABLE 3-2 Nominal Hazard Zone Radius Table 3-2 lists calculated distances for the CINCINNATI Laser System - Fiber Laser. This calculation assumes that the object being hit reflects all of the energy (the worst-case situation). The calculated distance, called the Nominal Hazard Zone Radius in the ANSI Z136.1 standard, was obtained using the method shown in this...

    determining the nature and composition of the fumes being released. A qualified professional should determine the need and subsequent design of a device to eliminate poisonous emissions from the ventilation exhaust. As mentioned previously, the process generates debris and fine particulate. This material should not be allowed to accumulate in the duct leading to the final exit point or control device.
  • Page 35 Cylinders should not be stored near elevators, gangways, stairwells, or other places where they can be knocked down or damaged. • Oxygen cylinders should not be stored within 20 ft. (6 m) of cylinders containing flammable gases or near the location of other highly combustible materials. Cylinders are not designed for temperatures in excess of 130°F (54°C).

  • Page 36: Cryogenic Liquid

    REGULATORS Pressure regulators must be used on cylinders to maintain a uniform gas supply at the correct pressure. The oxygen regulator should be equipped with a safety relief valve or be so designed that, should the diaphragm rupture, broken parts will be contained. Workers are advised to stand to one side and away from regulator gage faces when opening cylinder valves.

  • Page 37: Training

    GENERAL SAFETY PRACTICES The properties of cryogenic liquids affect their safe handling and use. • Always handle cryogenic liquids carefully. They can cause frostbite on skin and exposed eye tissue. When spilled, they tend to spread. The vapors emitted by these liquids are also extremely cold and can damage delicate tissues.

  • Page 38: Warning (Awareness) Lights

    • Do not climb on or between work pallets while DRIVE power is on. Severe injury can result from being trapped between moving pallets. Exercise extreme caution when pallet movement is performed. Remember that when the “Pallets Not Ready” button is not illuminated, the pallets will switch automatically when the cutting program commands the proper code.

  • Page 39: Safety Signs

    A six- digit number, usually located in the lower right corner, identifies all signs installed on machines by CINCINNATI INCORPORATED. If any of these signs become damaged or defaced, new ones should be ordered by contacting the factory or the nearest CINCINNATI Sales and Service Office.
  • Page 40 DANGER - LASER RADIATION (830137) This sign is mounted above the cutting head assembly on Z-axis block cover. This sign warns that if the cutting head is removed and the breakaway interlock is defeated, then laser radiation may be present. HIGH STRENGTH MAGNETIC FIELD (921533) This sign warns that a high strength magnetic field is present.
  • Page 41 The right side of the sign warns that laser cutting may form poisonous fumes, and that the nature and ventilation of these fumes must be determined. This sign is mounted at three places: one sign is on the operator’s and non-operator’s side of the cut area enclosure and third sign is mounted on the rear of the cut area enclosure.

    In order to accurately represent the Y = zero location along the sheet, these stops are cut by the machine. The following procedures must be completed before the Y = zero stops can be cut: • LASER SETUP, ELECTRICAL (by CINCINNATI Laser Service) specifically setting of Y-axis Home Offset. • LENS CENTERING •...

    X AND Y-AXIS SQUARENESS The CINCINNATI Laser - Fiber Laser gantry has linear encoder feedback on each of the X-axis servo systems. To make the Y-axis travel perpendicular to the X-axis travel, the “home” position of one X-axis encoder is adjusted relative to the other.

  • Page 55 3. The position of the X-stop pin is checked by cutting the sheet at a programmed machine location away from pin and measuring the actual distance from the pin surface to the edge of the cut. To accurately interpret the measurement, the kerf width must also be known. First cut a test square or similar test cut out on the sheet (away from the X-stop pin area) and measure the kerf width with a feeler gage.
