The conditions listed above are based on approximately 1xDc thickness of part with rigid work holding. 2. Conventional cut is recommended at part side for good surface finish. 3. Milling speed can be increased by 20-50% with the use of appropriate cutting oil. 4. Please provide appropriate measures against dust (Such as vacuum dust collection). 5. Depending on the workpiece thickness and form as well as work holding, vibration may occur. When it occurs, please adjust RPM and feed rate. 6. Kevlar laminate machinability can vary greatly by fiber and resin. If hole quality is not achieved with the feed rates provided above, reducing the feed rates may produce better quality surfaces.
