Hi everybody,
I just love lithophanes and for anyone who hasn't seen one then why not make your own.
This low resolution lithophane (comprising of 172 horizontal lines) was cut using a 2mm dia ball nose milling cutter. The material used is 3mm thick, white, opal, ‘plexi-glass’ and the depth of cut ranges from zero to 2.5mm. The maximum ‘step over’ was set to 0.5mm and the cutting was completed in a one depth pass with a total cutting time of about 45 Minutes. The actual size of the blank is 100mm x 86mm and the start point (X zero and Y zero) is dead centre of this. The Z axis zero point is with the cutter just clear of the surface of the work. Depending on your spindle speed you may wish to adjust the feed rate that is currently set at F450.
Best regards, Cooperman.
