The SR-100 sheet router from Haas Automation is a gantry-style, three-axis CNC machine with travels of 100" × 52" × 8" (XYZ). It accommodates 4' × 8' sheets of material and accepts ISO standard G-code programming through the company’s full-function CNC control.
The router is equipped with a 24,000-rpm, 5-hp (continuous) 30-taper spindle for cutting and drilling various plastics, sheet metals and other light materials. An optional 10-pocket ATC is available for unattended operation. Other high-productivity options include high speed machining with look-ahead, a hard disc drive with Ethernet interface, a remote jog handle and full fourth-axis capability.
The open-frame design of the router’s steel-beam base allows users to design their own table and fixturing specifically to meet their individual needs (a 1"-thick MDF table is standard). The overhead gantry assembly travels the full length of the fixed table on precision, low-friction linear guides, resulting in accurate positioning, the company says. Brushless servomotors on all axes produce rapids as fast as 2,000 ipm in X and Y axes for fast cycle times. The standard configuration includes a 15'', color LCD monitor and a USB port.
The forces involved in the milling process can be quantified, thus allowing mathematical tools to predict and control these forces. Formulas for calculating these forces accurately make it possible to optimize the quality of milling operations.
