The main purpose of the fixtures is to hold and locate the workpiece during any machining operation and to provide repeatability, accuracy, and interchangeability in the manufacturing of products. Some important points about fixtures: Fixtures are used in multi-dimensional machining like milling, grinding, turning, etc.
Process capability compares the output of an in-control process to the specification limits by using capability indices.The comparison is made by forming the ratio of the spread between the process specifications (the specification "width") to the spread of the process values, as measured by 6 process standard deviation units (the process "width").
THREAD GRINDING-Produce very accurate threads on hardened materials-Three basic methods are used. 1. Center type grinding with axis feed: (Work spins slower) similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool. (even multiple shaped grinding wheel can be used ).
Introduction to Grinding and Drilling in Basic Workshop Technology Introduction 1. The process of removing material from a piece of work by means of rotating abrasive wheel is known as grinding. Grinding wheel is mounted on the spindle and rotates on it.
A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.
Light microscopy has been used for many decades to provide insight into the microstructure of materials. Brightfield (BF) illumination is the most common illumination technique for metallographic analysis. In incident BF, the light path comes from the light source, passes through the objective lens, is reflected off the surface of the specimen, returns through the …
