  • Page 18: Safety Notes For Set-Up Procedure

    Safety notes for set-up procedure 1. During the following procedures the laser is emitted from the torch. Since the operator is required to view the reflected beam at a close proximity, plastic safety glasses are mandatory. 2. Confirmation of the laser discharge in a ready state can be determined by the "cw" or "pulse" led on the operating panel.

  • Page 52: Getting The Most Consistent Cut

    Getting the Most Consistent Cut When test cutting a new part or new material, the preferred method is to cut a small circle or square before cutting the part. If a difficult geometry is present in the part, such as a material thickness hole or a small notch, simulate the cut in a test square to find the best cut condition.
  • Page 53 limit of the window for assist gas pressure. Now lower the assist gas pressure until the lower limit of good cutting is found. If the cutting window was found to lie between 2.0kgs and 5.0kgs, set the pressure to 3.5kgs which is the middle of the window in this case.

    EFFECT OF FOCUS POINT ON CUTTING MILD STEEL WITH OXYGEN When the machine set-up procedure is performed the focus point of the lens is adjusted to a specified position either above or below the surface of the material. When cutting mild steel the focus point is raised higher as the thickness increases.

  • Page 66: Steel Plate Cutting Techniques

    STEEL PLATE CUTTING TECHNIQUES WHEN CUTTING STEEL PLATE THERE ARE SEVERAL PROGRAMMING TECHNIQUES WHICH HELP MINIMIZE THE EFFECTS OF EXCESS HEAT CAUSED BY PIERCING AND CUTTING THE MATERIAL. THESE TECHNIQUES INCLUDE THE FOLLOWING: HEAT BARRIER SEGMENTS THIS TECHNIQUE INVOLVES CUTTING A STRAIGHT LINE BETWEEN ROWS OF PARTS IN ORDER TO STOP HEAT TRANSFER BETWEEN ROWS.
  • Page 67 PART LAYOUT EXAMPLE THIS LAYOUT EXAMPLE SHOWS THE FOLLOWING TECHNIQUES: 1> HEAT BARRIER SEGMENTS. 2> STAGGERING INTERNAL GEOMETRY’S. 3> CHAIN CUTTING. Depending on the size of the part and spacing of the internal cut outs, sometimes all internal geometry can be cut for each part before cutting the perimeter.

  • Page 68: Program Restart Function

    PROGRAM RESTART FUNCTION During operation, if “RESET” is pressed, the program will restart at the beginning unless this procedure is followed. This procedure will allow operation to continue from the point it was at when an alarm occurred without repeating what has already been cut.
  • Page 69 MACHINE GRAPHICS (L PLUS CONTROL) 1> Position the axes close to home position, but not so close that the part to be simulated would not fit on the table. The L Plus control has a feature which looks ahead in the program to see if there are any movements that would cause an overtravel.

  • Page 70: Cutting Plastic Coated Metals

    CUTTING PLASTIC COATED METALS When cutting plastic coated metals with a contact style profiler, sometimes the plastic coating will “balloon” due to the pressure of the assist gas. This may cause the stylus foot to ride on the plastic causing the focus point to be lost and subsequently the cut is lost or becomes poor.
  • Page 71 PRE-BURNING ENTIRE PART (FOR LARGE HOLES AND PARTS) When cutting thick materials which require assist gas pressures in excess of 6.0 kg/cm , there may be ballooning at any point during cutting. For these materials it is possible to pre-burn the entire part before cutting, in order to create a channel through which the assist gas can escape without causing the coating to separate.
