1. Structural elements to be machined surface - the workpiece to be removed on the surface. The surface has been machined ---- workpiece after cutting the surface produced by the tool. Transition surface (synonym: machined surface) - The part of the workpiece formed by the cutting edge that will be cut off in the next pass, next revolution of the tool or workpiece, or by the next cutting edge. Front (Synonyms: rake face) - the surface through which the chips on the tool flow. It acts directly on the metal layer being cut and controls the cutting edge along which the chips are discharged. Behind (synonym: flank) - The surface opposite to the surface produced in cutting on the workpiece. The main back (synonym: the main flank) ---- tool on the front of the intersection of the main cutting edge to form the back. It is facing the transitional surface. Vice back (synonym: vice after the knife) ---- Tool on the front of the intersection of the formation of the Deputy cutting edge behind. It faces the machined surface. The main cutting edge - starting at the point where the main declination angle is zero on the cutting edge and having at least one cutting edge intended to cut out the entire cutting edge of the transition surface on the workpiece. Minor cutting edge - The cutting edge, other than the main cutting edge, also starts at the point where the main deflection angle is zero at the cutting edge but extends away from the main cutting edge. 2. Tool Angle Reference system cutting plane ---- by the cutting edge selected point tangent to the cutting edge and perpendicular to the plane of the base surface. Main cutting plane Ps ---- The plane that is tangent to the main cutting edge and perpendicular to the base plane by the cutting edge. It is cut at the transition surface, that is to say it is made up of the cutting speed and cutting edge tangent plane. Deputy cutting plane ---- by the cutting edge selected point and the minor cutting edge tangent and perpendicular to the base plane. Base Plat Pt - The point selected by the cutting edge perpendicular to the plane of the resultant cutting speed. In the stationary reference frame of a tool, it is a plane or axis over which the selected point of the cutting edge passes, parallel or perpendicular to the tool, suitable for mounting or positioning during manufacture, sharpening and measurement, and generally has its orientation perpendicular to The assumed direction of the main movement. Assumed working plane ---- In the stationary reference system of the tool, it is a plane that is selected and perpendicular to the base of the cutting edge, parallel or perpendicular to the tool, suitable for mounting or positioning during manufacture, grinding and measurement The axis, in general, has its orientation parallel to the assumed principal direction of motion. Plane Pn ---- Select the point by the cutting edge and perpendicular to the plane of the cutting edge. 3. Tool angle front angle ---- the angle between the front and the base surface. Clearance - behind the angle between the cutting plane. Wedge angle - the angle between the front and back. Main declination - the angle between the principal cutting plane and the assumed working plane, measured in the base plane. Vice declination ---- Vice cutting plane and the assumption of the angle between the working plane, measured in the base surface. Knife angle - the angle between the main cutting plane and the secondary cutting plane, measured in the base plane. Inclination - The angle between the main cutting edge and the base surface, measured in the main cutting plane.
