Given the long machining time, we ultimately decided to do a 1/3-scale test cut from a stack of 0.01" brass sandwiched between 0.25" aluminum. The perimeter of this toolpath measures 17.5 inches. With an expected cut speed of 0.18 inches/minute, the expected cut time is just about 100 minutes or 1 hr 40 mins.
