Preface:
Power generation is an important issue today, especially on the West Coast. Demand is outweighing supply because of lack of incentives for the utilities industry to build additional power plants over the past 10-20 years. Electrical innovations (such as the personal computer) were not accounted for in earlier predictions of power utilization and, now, the country is in dire need of streamlining the current power plants while pushing through as many applications as possible for new power plants. In response to this situation, ....etc

CAM Systems & CNC Machine
History
1955 - John Parsons and US Air Force define a need to develop a machine tool capable of machining complex and close tolerance aircraft parts with the same quality time after time (repeatability). MIT is the subcontractor and builds the machine for the project
1959 - MIT announces Automatic Programmed Tools (APT) programming language
1960 - Direct Numerical Control (DNC). This eliminates paper tape punch programs and allows programmers to send files directly to machine tools

NC, CNC, DNC Machine
Numerical Control (NC) refers to the method of controlling the manufacturing operation by means
of directly inserted coded numerical instructions into the machine tool.
Numerical control (NC) refers to the automation of machine tools that are operated by abstractly programmed commands encoded on a storage medium, as opposed to manually controlled via handwheels or levers, or mechanically automated via cams alone.
The major advantages of NC over conventional methods of machine control are as ....etc

PRODUCTIVITY IMPROVEMENT ON COPY TURNING MACHINE, THROUGH CYCLE TIME REDUCTION
OUR ACHIEVEMENTS
We reduced the cycle time required for a valve on
CT machine from 24 seconds to 22 seconds.
The reduction of 2 seconds in the cycle time has
resulted in following changes.
Monthly turnover increased by Rs 5,62,500.
Yearly turnover increased by Rs 67,50,000.
AIM OF THE PROJECT
To increase the valve production from 950 to 1050 valves per shift on Copy turning machine by reducing the cycle time require ....etc
