• Now have computer numerical control (CNC) machines • Machining operations are a system consisting of: •Workpiece –material, properties, design, temperature •Cutting tool –shape, material, coatings, condition •Machine tool –design, stiffness & damping, structure •Fixture –workpiece holding devices
The lathe is a machine tool used principally for shaping pieces of metal (and sometimes wood or other materials) by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing the cutting action.
machine guard designers and fabricators, and all others with an interest in protecting workers against the hazards of moving machine parts. It identifies the major mechanical motions and the general principles of safeguarding them. Current applications of each technique are shown in accompanying illustrations of specific operations and machines.

Machine Operators. The employees who operate machines for the purpose of work are collectively known as machine operators. They are the ones who are tasked to operate equipment and big machines needed for the operations of the business.
Apr 04, 2015 · Though drilling is the primary operation performed in a drilling machine, a number of similar operations are also performed on holes using different tools.The different operations that can be performed in a drilling machine are: Drilling; Reaming; Boring; Counterboring; Countersinking; Spot facing; Tapping; Trepanning; Drilling
CHAPTER 1. PRINCIPLES OF OPERATION OF SYNCHRONOUS MACHINES. The synchronous electrical generator (also called alternator) belongs to the family of electric rotating machines. Other members of the family are the direct- current (dc) motor or generator, the induction motor or generator, and a number of derivatives of all these three.
Jan 14, 2015 · Operations of Lathe Machine: Drilling: The drilling is an operation of creating a hole in the workpiece with the aid of a drill. In the drilling operation, the drill machine is normally fed into the workpiece which rotates by rotating the hand wheel of the tail stock.
Milling. Milling is one of the fundamental operations in machining. This manufacturing process is less accurate than the turning processes because the degree of freedom is high. Milling fabricates the object which is not axially symmetric. A milling machine is required for this purpose along with a fixture, cutter and of course the workpiece.
A lathe is a machine that rotates the piece on the axis in order to perform various operations like cutting, facing, knurling, deformation and more. Metal spinning, thermal spraying, woodturning and metalworking are the common operations performed with a lathe machine. One can …

Apr 03, 2015 · Various Types of Operations Performed in Lathe Machine Posted on April 3, 2015 August 29, 2015 by Peter Paul Various operations are performed in a lathe machine other than plain turning.
Milling Machine The milling machine has always been one of the most versatile machine tools used in industry (Fig. 5). Operations such as milling, contouring, gear cutting, drilling, boring, and reaming are only a few of the many operations which can be performed on a milling machine. The milling machine can be programmed on three axes:
Installation of the machine, requires that the machine be un-crated, placed in its proper position and secured in place with the caster locks . Operation may begin once strap of the proper size is loaded and the power cord is plugged into the appropriate electrical outlet. Remove the screw on the top cap of speed reducer for ventilation.
machines. Operators load the CNC machines with instructions or programs. They then determine the speed and feed ratios as well as the size and position of cuts. They select, measure, install, and secure the tools and attachments the machines will use, reading blueprints and using their knowledge of the job to select the proper tools.
The same part can be reproduced to the same degree of accuracy any number of times if the CNC program has been properly pre- pared and the computer properly programmed. The operating commands which control the machine tool are executed automati- cally with amazing speed, accuracy, efficiency, and repeatability.
direction for angular and helical milling operations. The universal machine can be fitted with various attachments such as the indexing fixture, rotary table, slotting and rack cutting attachments, and various special fixtures. RAM-TYPE MILLING MACHINE The ram-type milling machine is characterized by a spindle mounted to a movable
