GENERAL OPERATING GUIDELINES THESE OPERATING GUIDELINES ARE RECOMMENDED STARTING POINTS FOR SAFE EFFECTIVE PERFORMANCE IN A VARIETY OF MATERIALS The parameters outlined on the following pages represent recommended general operating guidelines. They are intended to act as starting points as you look for the optimum operating parameters for a specific application. Optimum parameters for any application are bound to vary according to the unique combination of variables which may be present in that particular application. Such variables might include the machine tool condition rigidity of the workpiece and fixturing the work material condition the precise hardness and machinability of the material and the shape and finish requirements of the workpiece to name a few. Once the application is operating reasonably well and safely adjustments to these guidelines can be made based on variables present and the performance of the tool. Extended length end mills require special operating parameters. They are NOT intended for channel cutting. Feed rates must generally be reduced due to their length-to-diameter ratios. Always use the shortest extension possible for best performance. Refer to "Rigidity Analysis on page 310. When ball nose end milling two critical parameters are directly affected by the Depth of Cut (DOC): cutting speed in Surface Feet per Minute (SFM) and chip thickness. It is necessary to recognize these factors and to follow the guidelines relating to them. Refer to "Ball Nose Chip Thinning on page 312. For additional information regarding specific grades refer to the grade chart on page 322. If you have questions regarding a specific application contact your Ingersoll Cutting Tool Company sales engineer for assistance. Subject to technical changes. 345
