Helical and Thread Mill Interpolation
14 Helical Interpolation in a Mill In a mill the concept is identical to that of the Yaxis lathe seen in the previous paragraph; the only difference is in the definition of the work plane on which the circular interpolation is carried out In this case the work plane used is defined by the function G17 (XY plane) Fig 4 Helical path The spiral jet mill is suitable for the fine and ultra fine size reduction of materials up to a Moh’s hardness of 3 that display brittle crystalline grinding characteristics They are typically used in applications where a ultrafine portion is required The spiral jet mill is simple in design, consisting of a flat cylindrical grinding chamber with several nozzles arranged tangentially in the A Review on Micronization Techniques JALAY T JOSHIWhen you plane a 10 inch wide board for example, the traditional straight knives will cut these 10 inches straight off which also causes a high noise level Because of the spiral pattern, a SHELIX head will remove only 15mm (about ½ inch) at any given time, causing a decreased noise level While the noise level reduction is measurable in db, we cannot put a general number on it as it depends SHELIX Helical Cutter Heads
