Machining VYCOM This chapter details various methods of machining Designboard, Playboard and Seaboard as part of processing high-density polyethylene (HDPE) material into its final form. Common metal and woodworking tools and machinery can be used, depending on the specific application for the finished product. Cutting Vycom HDPE material can be cut with a table saw, radial arm saw, CNC router, band saw, or panel saw. With any cutting process, the key is good sharp tools and adequate chip removal, which helps eliminate heat build-up. A dull tool or improper feed rate can lead to rough edges and heat build-up to the point where the chips start to melt and refuse. Always cut a test piece prior to a production run. Circular saws Generally, carbide tipped blades are recommended. The following settings are useful starting points (Figure 1a); • Rake angle: 0° to 15° degrees • Clearance angle: 10° to 20° degrees • Cutting speed: 8,000 to 12,000 feet per minute • Feed: 70 to 90 feet per minute • Tooth pitch: 0.080” - 0.040” Band Saws Figure 1a 1 High speed steel blades normally recommended for wood or plastic (hook type) can be Copyright 2013 Vycom 07
