Lecture 8 | Program for Taper Turning Operation with -Ve and +Ve Radius | CNC Machining Programming
Taper turning is a machining process used in manufacturing and engineering to create a gradual reduction in the diameter of a cylindrical workpiece from one end to the other, resulting in a conical or tapered shape. This is achieved by positioning the cutting tool at an angle relative to the workpiece's axis, leading to a uniform change in diameter along the length of the workpiece. Taper turning can be applied to the workpiece's external or internal surfaces, depending on the desired taper direction. This machining operation serves a diverse range of purposes across a number of industries, from improving functionality and aesthetics to ensuring proper fits and alignments in assemblies.
A taper is created when a straight line cuts a section of the surface of a solid cone. This is achieved by consistently varying the diameter of the workpiece over the length being machined. In the world of CNC machining, this function is performed by taper turning. It could be either external, where the tapered surface is on the outside of the workpiece, or internal, where it's on the inside. There are multiple methods to achieve it, such as the method of taper turning, compound rest, form tool, taper attachment, and the tailstock set over method. However, as CNC machines typically do not have a taper turning attachment, there is a different procedure to create a taper. Herein, the secret lies in the machine's capability to move multiple axes simultaneously.
