The reason to have circular motion with the turning tool is for the tool tip to always follow the center of the eccentric diameter, having the same distance at any given angle, meaning the tooltip will always be on center of the eccentric. More clarification please XD. I want to know the easiest way of doing this. Uly. Dec 16, 2019 · Eccentric turning on a lathe refers to the turning off the center or not on the normal center axis, it can be done on 3 jaw self-centering chuck or 4 jaw chuck in different situations, the 4 jaw chuck with independently moved jaws allows parts to be moved off-center.. "/>. Fast and consistent accuracy up to 300 mm Taper Turning job on the lathe. It’s useful in threading on the lathe workpiece inside as well as outside. Any length of the lathe workpiece can be tuned. At the set, the position accessory can be left. With taper turning, we can easily do narrow boring on the lathe machine. Mar 03, 2021 · Eccentric turning, also known as offset turning, is a type of lathe operation. It is typically used to machine parts with features that are not concentric to the spindle axis, such as the eccentric drive of a steam engine and a crankshaft. The main difference between turning and eccentric turning is the center of rotation of the workpiece. Limitations: The attachment is helpful in eccentric turning of jobs of 75 mm diameter and 150 mm length. For heavy jobs, the attachment will become lighter hence they have to go to eccentric turning lathe. If these attachments are produced on mass scale, by machine tool manufacturers and supply with the lathe that will be highly. Contour turning is a machining operation by which we can make a three-dimensional reproduction of the shape of a template by controlling the cutting tool. Eccentric turning. When we perform the turning operation of the workpiece not on the normal center axis, instead of at an offset to the center axis is called Eccentric turning. Grooving. I have a 2 axis lathe with encoder on the spindle. I use SolidWorks/SolidCAM to generate g-codes. No problems at all. Only thing that I wasn't been able to get SolidCAM to post a simple eccentric turning program. So I guess SC doesn't support eccentric turning at all. Question is how can I write a program to cut a piece like in the attached image?.
