The speeds & feeds listed here are conservative
recommendations for initial setup. In actual use, depending on the
machine environment and workpiece material, significantly higher
speeds & feeds may be achievable. Using these speeds & feeds
as a starting point, cutting conditions can be gradually adjusted
until the optimum settings for the application are found. Questions?
