PENGARUH JARAK DAN PANAS SINAR LASER TERHADAP HASIL ENGRAVING PADA MATERIAL KAYU MENGGUNAKAN MESIN CNC LASER DIODE

Testing the effect of distance and laser beam heat on engraving results using two specimens as test materials, namely teak wood durian wood. The testing process is to make circles rectangles with a diameter 20 mm which are inputted into program followed by process. measured how many differences occur so that closest level precision obtained variations in beam. From test, it was found has more precise accuracy size 0.15-0.35mm, while for 0.2-0.4mm. With reference general tolerance medium sizes >6-30mm 0.2mm, best result use spacing 70mm. testing, 0.05 - 0.7mm, 0.1-0.8mm. 0.2mm >30-120mm 0.3mm, temperature 400C 0.05mm.
