Industrial pins are varieties of fastening hardware meant to couple, align, mount, assemble, or penetrate two workpieces. The operation of the pin depends on design and employment, but industrial pins can be categorized into several categories, such as: hitch and linch pins; cotter pins and wire clips; spring pins; locating and fixturing pins; and specialty pins.
MACHINING OPERATIONS AND MACHINE TOOLS
Machining Operations and Part Geometry Each machining operation produces a characteristic part geometry due to two factors: 1. Relative motions between the tool and the workpart •Generating –part geometry is determined by the feed trajectory of the cutting tool 2. Shape of the cutting tool •Forming –part geometry is created by the

Introduction to Machining: Milling Machine
mill work that requires great accuracy. An edge finder helps in finding the edges. •800-1200 spindle RPM is recommended. •To use an edge finder, slightly offset the two halves so they wobble as they spin. •Slowly move the workpiece towards the edge finder. •The edge finder will center itself, then suddenly lose concentricity.

Size reduction - SlideShare
Size reduction of solids – converting large particles into smaller/fine particles of the same material. Size reduction is brought by application of force on larger particles. Types of forces applied: (i) Compression (ii) Impact, and (iii) Shear Size reduction process is also known as comminution or grinding.
