PSS-3000 Optical Sheet I Fabrication PSS-3000 SHEET CUTTING RECOMMENDATIONS I. Using a Laser Cutting Tool All PSS-3000 sheets can be cut to any shape or size using a computer controlled laser with general tolerance of 0.1 mm. See table to the right for laser settings using a Universal Laser Systems ILS 12.150D with two 50W laser tubes and air assist. LASER SETTINGS PSS-3000 SHEET THICKNESS IN CUTTING SPEED 0.030 27 0.040 25 0.060 18 0.080 12 0.118 7.5 0.195 4.8 0.240 4 All vector cutting performed at 100 power. II. Using a Computer Numerically Controlled CNC Cutting Tool Customers that are used to processing plastic material that is softer than PSS-3000 sheet may have to increase the RPM of their milling machine and adjust milling linear speed depending on the thickness of the sheet. Otherwise the risk of breaking or chipping the PSS-3000 sheet increases. Specific details are below 1. CUTTER SPINNING SPEED The cutter spinning speed can be set as high as possible. In general 5 mm diameter cutter 25000 rpm 1 mm diameter cutter 40000 rpm Rotation of Tool 2. CUTTER ROTATION DIRECTION For best results the cutter tool should move in the same direction as rotation of tool.

CUTTER LINEAR DIRECTIONAL SPEED The X Y and Z linear speeds will depend on how much material is going to be removed thickness and size reduction. 4. CUTTING SQUARE ANGLES 90 tool movement is suggested for cutting square angles and to continue the cutter past the end of the sheet as shown to the right. 5. COOLING REQUIREMENTS Cooling by liquid is not needed. Air flow to cool the cutter and remove the cut material is recommended. 6.

Using a Knife Blade to Score PSS-3000 Sheet A Tantung or Widia blade can be used to score PSS-3000 sheet. Note that thinner sheets 1.0mm may chip or crack when attempting to break the sheets apart. 2014 ESP. All Rights Reserved.
