The difference between steam turbine and reciprocating engine is given bellow: Steam Turbine Reciprocating Engine In steam turbine working fluid is steam. In reciprocating engine working fluid is fossil fuel. Steam turbine efficiency is high and it is more than 60 %. Reciprocating engine efficiency is low and it is 30 to 40 %. Steam turbine vibration is low. But reciprocating engine vibration is high. Steam turbine has proper balancing. Reciprocating engine is unbalance or weak balance. Steam turbine lubrication is negligible. Reciprocating engine lubrication is major. Steam turbine design is simple. Reciprocating engine complex and compact. It is design for high power output. It is design for low power output. Steam turbine generates uniform power. Reciprocating engine do no

Classification of structure machine tools: According to purpose structure of machine tools are classified as 1.       Bed, frame works. 2.       Bases bed plates. 3.       Housing, boxes, columns etc. 4.       Casing and covers.                                        Figure: Open structure machine tool  By following manufacturing method structure of machine tool is defined as  1.       Welded 2.       Partly welded 3.       Cast 4.       Partly cast By following the transmission of operational load 1.       Open structure 2.       Closed structure

Chemical Machining: Chemical machining is the process used to dissolve the workpiece material in the chemical solution. Since the chemical solution used have the ability to dissolve all the workpiece material.                                                  Figure: Chemical Machining What do you mean by structure of machine tool? Definition of structure of machine tool: Housing, columns, bed and bases are combined called structure of machine tool. Structure of machine is called backbone of machine tool. It is also ¾ weight of the machine tool.

Difference between Ultrasonic Machining (USM) and Abrasive Jet Machining (AJM) is given bellow: Ultrasonic Machining (USM) Abrasive Jet Machining (AJM)      1.       Ultrasonic Machining (USM) process use ultrasonic wave. 1.        Abrasive Jet Machining (AJM)    does not use ultrasonic wave. 2.       USM process use abrasive slury cutting edge. 3.       AJM process use steam of abbrasic particles as cutting ede. 4.       By Ultrasonic Machining (USM) process machining brittle and hard material. 5.       Abrasive Jet Machining (AJM)    process machining brittle and Fragile material. 1.       Ultrasonic Machining (USM) process does not require any nozzle to flow abrasive slurry. 6.       Abrasive Jet Machining (AJM)    required nozzle to flow air abrasive particles. 2.       The Ultrasonic Machining (USM) process does not any heat generation.
