- cutting force
Engagement of a tool’s cutting edge with a workpiece generates a cutting force. Such a cutting force combines tangential, feed and radial forces, which can be measured by a dynamometer. Of the three cutting force components, tangential force is the greatest. Tangential force generates torque and accounts for more than 95 percent of the machining power. See dynamometer.
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
With variable index and unique flute geometry, the OSG HY-PRO® CARB VGM series features unequal flute spacing which reduces vibration during machining by altering the timing of each flute engaging in the workpiece. In addition, a sharp rake angle, high helix and adjusted core diameter maintains excellent cutting edge sharpness and tool rigidity to promote smooth, stable cutting with low cutting force.
