These guidelines may require variations to achieve optimum results. Above parameters are based on ideal conditions. For smaller taper machining centers, please adjust parameters accordingly on 1/2" diameter. For tools with reach 4.5xD, reduce fz by 30% and use lowe range of cutting speed as starting condition. Tools with chip splitters can be used as finishers.
