TECHNICAL TERMS AND ANGLES Turning Holders R50 Terms and Angles of Turning Toolholder Shank Width Front Relief Angle Function of Tool Angles Tool Angle Name Function Effect Rake Angle Side Rake Angle Affects cutting force, cutting heat, chip evacuation and tool life. If it is positive (+) angle, sharper cutting performance is obtained. (less cutting resistance, less edge strength) Positive (+) angle is recommended for easy to machine workpieces or thin workpieces. Smaller rake angle or negative (-) angle is recommended when a stronger edge is required like scale cutting or interrupted cutting. Inclination Angle Relief Angle Front Relief Angle Side Relief Angle Prevents the tool’s contact to the workpiece surface, except the cutting edge. When it is small, the cutting edge becomes strong, but the wear at relief faces may shorten the tool life. Cutting Edge Angle Cutting Edge Angle Affects chip control and the direction of cutting force. When it is large, chip thickness becomes thick and chip control improves. Approach Angle Affects chip control and the direction of cutting force. When it is large, chip thickness becomes thin and chip control worsens, but cutting force is dispersed and edge strength improves. When it is small, chip control ability improves. Minor Cutting Edge Angle Prevents friction between cutting edge and work surface. When it is large, edge strength deteriorates. Toolholder Rigidity 1. Flexure of Toolholder 2.

Minimizing toolholder shank over hang as much as possible is important as well as shank's sectional square measure. 8°°.823.7284 Visit us online at Side Rake Angle Side Relief Angle Cutting Edge Heig Minor Cutting Angle Corner Radius Total Length Approach Angle Inclination Angle Shank Height 64xFx(LPR)3 64xkxapxfx(LPR)3 3xExrc x (DCON)4 3xExrc x (DCON)4 Symbol Young ratio Depth of Cut Specific Cutting Force Overhang F Cutting force N Clamp Screw (F = kxapxf) Cuttinq Force F Supporting Point Overhang LPR Amount of Displacement Sleeve
