FOCUS ADJUST

Call up or input the program for focus adjust. Load a sheet of 16 gauge(.060"), large enough to be held by all three clamps and touch both X gauge blocks. Set the G93 for the position you are going to cut. Open the oxygen bottle and set the regulator to 100psi. Set O2 low and O2 high to .5kg/cm2 and 1.5kg/cm2 respectively.

Press the Custom button. This will boot into the Material List. Cursor to "SPC1.5", press Input and then the Open soft key. This will bring up the Cutting Condition screen. Cursor down to a condition, 1 through 8, that has a feedrate of around 150ipm. Change the power to 800watts by moving the cursor to the power column, keying in the number 800 and pressing insert. Move to the frequency and change to 2000Hz. Set duty to 100%. Press the "save" soft key to store the changed data.

Press Function and Program buttons to get back to the program text. In the "Focus Adjust" program, set the M102 (material spec) and corresponding "E" code that was selected from the above procedure.

Turn off the HeNe. Go to Auto mode. Move the focus down 2mm by pressing the -B button and watching the dial indicator on the cutting head.

Press the Start button. After it cuts one line move the focus up 0.5mm and press start. Repeat this process until the lines appear narrower then wider.

Reset the control. Retract the axis.

Using a feeler gauge, determine which line is the narrowest. Move the focus to the point which corresponds to that line. Focus is now set at zero, so move the dial on the indicator so "0" is at the needle.

FOCUS ADJUST

Call up the FOCUS ADJUST Program. Load a 40" x 40" sheet of .060" Cold Roll. If the Customer Does not have that size sheet, the one they provide must be held by all Three Clamps and Touch both X Locate Pins. Set theG93 X and Y for the Position you are going to start cutting. Open the Oxygen Bottle and set the Regulator to 100psi. Set OXYGEN (LOW) and OXYGEN (MID) to .5kg/cm2 and 1.5kg/cm2, respectively, using the Manual Assist Gas Select Switch and the corresponding Regulator.

Press the CUSTOM Button. This will bring up the Material List or Cut Condition Screen. If it is on the Cut Condition Screen, press the Mtrl ListSoft Key. Cursor to SPC1.5 (SPC, denotes Cold Roll Steel and 1.5, denotes the Material Thickness), press the INPUT Button and then the Open Soft Key. This will select that Material. Press the Cut Cond. Soft Key to bring up the Cut Condition screen. Cursor down to a Condition, 1 through 9, that has a Feedrate of around 150.00. Change the Power to 800 watts by moving the Cursor to the PWR (S) Column, Keying in 800 and pressing the INPUT Button. Move to the Freq. Column and change to 2000. Set Duty (%) to 100. Press the Save Soft Key to store the changed Data.

Press the PROG button to get back to the PROGRAM Text. In the FOCUS ADJUST Program, set the M102(Material Spec) and the corresponding E code.

Turn the SHUTTER ENABLE Key Switch to ON. Go to MEMORY Mode. Move the Focus Down 3mm by adjusting the FOCUS ring on the cutting head.

Press the START Button. After it Cuts one Line, move the Focus Up 0.5mm by adjusting the FOCUS ring. Press START. Repeat this process until the Lines appear to become narrower, then widen.

Reset the Control. Retract the Axes.

Using a Feeler Gauge, determine which Line is the narrowest. Move the Focus to the point which corresponds to that Line. Focus is now set at Zero, so move the ARROW on the Cutting Head to 0.

Notice the Focus column on this cutting condition. You will be changing this parameter to adjust the focus point a bit later in this procedure. Press theSave Soft Key to store the changed Data.

Press the PROG button to get back to the PROGRAM Text. In the FOCUS ADJUST Program, set the M102(Material Spec) and the corresponding E code.

Turn the SHUTTER ENABLE Key Switch to ON. Go to MEMORY Mode.

Press the START Button. After it Cuts one Line, move the Focus Up or down 0.5mm by changing the value of the focus on the cutting condition 1-9 that was used in the previous steps. Repeat this process until the Lines appear to become narrower, then widen.

Reset the Control. Retract the Axes.

Using a Feeler Gauge, determine which Line is the narrowest. Move the Focus to the point which corresponds to that Line. Focus is now set at Zero. Select the Laser Parameter screen, and set the standard position to your new value.
