- Page 13 CREATING CURVES Your sheet metal machine can easily create constant radius curves in sheet metal up to 1 mm in thickness. The method of creating a specific radius is a trial and error process. Due to the many variations among metal workpieces, no single configuration of the rollers will reproduce the same curve in all materials.

Page 14: Creating Cylinders
NOTE: If your workpiece has an undesired initial flat, as illustrated in Figure 19, you can remove it by flipping the workpiece around and pass it through the front of the machine so that the initial flat enters last. 4. Slightly tighten the diameter Fig. - Page 15 You can use the slip roll to create a Fig. 20 bend with the correct radius so that the two ends meet, forming a 150 mm diameter cylinder (Figure 20). NOTE: Performing multiple passes through the machine with gradual reductions in the curve radius produces better results than trying to make the curve in one or two...
