What are the car knives made of?
Three faces: the front face A gamma-cutting the surface of the outflow. A alpha, the surface of the transition surface. The second knife face A alpha - the surface opposite the processed surface. Two edges: main cutting edge and side cutting edge; Tip: main cutting edge and side cutting edge. The cutting part of the lathe consists mainly of the following parts: the front face A gamma-cuttings along the outward surface. A alpha, the surface of the transition surface. The second knife face A alpha - the surface opposite the processed surface. Main cutting edge - the edge of the knife facing the front edge of the main blade. Side cutting edge - the blade of the knife facing the front of the knife. The geometrical Angle of the tool is determined in the reference frame of a certain plane, which is usually orthogonal frame reference frame, the normal frame reference frame and the assumption working plane frame reference frame
Undertake the main cutting workpiece, which is cut off the transition surface in the workpiece. Side cutting edge, front and rear end of the line, it coordinates with the main cutting edge to remove the residual and eventually forms the finished surface. The tip. Lord, vice cutting edge joint part of the relatively few cutting edge, unless specified as a point, is the tool cutting part of the working conditions of the worst part.
A car knife is usually made up of two parts: the holding part and the cutting part. The holding parts are usually made of ordinary carbon steel, ductile iron and other materials. The cutting parts are made of various kinds of cutting tools, which can be made into various shapes according to need. The so-called face, the blade, the tip. The front edge of the knife, which is the cutting edge of the cutting. The rear edge of the knife is the surface of the surface of the machinable surface. And then there's the second one. Main cutting edge, front and back
Using the orthogonal plane reference frame, the reference surface is shown below: the base surface pr, the plane of the parallel or the vertical tool (or axis) of the cutting edge. Cutting plane ps - the cutting edge of the cutting edge is tangent to the cutting edge and is perpendicular to the plane of the base plane. Orthogonal planar Po - the cutting edge is selected at the same time perpendicular to the plane of the cutting plane and the base plane. For the frame reference frame, it is composed of the pr, ps, and pn three planes: the normal plane pn - the plane with the cutting edge selected and perpendicular to the cutting edge. Work for assuming plane frame of reference, consist of three plane pr, pf, pp, including: assume that working plane pf - cutting edge points selected direction parallel to the assumption that feed movement and vertical on the surface of the base plane
