The programmed tool is displayed in 3 dimensions on the screen and is an exact reproduction of the tool produced by the grinding machine. The Tool Studio Basic software can be used to manufacture and regrind endmills, drills, reamers and spherical cutters. End Mills For cylindrical and tapered shank type tools with included conical angle of up to 90° and the following end forms; Square End, Corner Chamfer, Corner Radius, Ball Nose, Double Radius and Beveled Corner Ball Nose with up to 4 MGM clearances. Corner Radius with 2 MGM clearances. Ball Nose Left/Left and Right/Right. Corner Radius Left/Left, Right/Right, Left/Right, & Right/Left. Wizards from 1 tooth up to 16 teeth (12 teeth for Ball Nose). Single Pass or Multi Pass fluting. Radius washout at flute end. • Automatic collision detection and Automatic Machine Move Optimization (AMMO) • Regrinding constant helix, constant lead, digitizing changing helix. • Equally and unequally indexed flutes. Ball Nose End Mills with S-Gash Wizard for cutting edge combinations 2/2, 3/3, 4/2 (End Teeth / Long Teeth) Grinding with outside diameter or side of the grinding wheel Start angle for generating definable chisel point. Rake angle up to 30° negative, definable at up to 10 points through the radius section. Drills 2 & 3 flute drills with cam relief, facet and Form E style points and the following gashing options; Conventional, split point, double split point, & radius and core style gashes. Coolant hole probing. Main cutting edge correction. Flute wash out feature. Reamers Reamers with short lead-in chamfer, long lead-in chamfer, or double lead-in chamfer. Straight, Left/Right, Right/Left, Right/Right & Left/Left Tool Studio Advanced Prerequisite: Tool Studio Basic The Tool Studio Advanced is an extension of the Basic Tool Studio software and gives more capability to create non-standard, custom or proprietary type tools.
