Numerical Control (NC) is a method of automatically operating amanufacturing machine based on a code of letters, numbers,and special characters.
The numerical data required to produce a part is provided to amachine in the form of a program, called part program or CNCprogram.
The program is translated into the appropriate electrical signalsfor input to motors that run the machine.

High Speed Machining (HSM)
![Page 24: MODULE 01 High Speed Machines](https://reader030.vdocuments.us/reader030/viewer/2022020311/5695d35d1a28ab9b029dae6e/html5/thumbnails/24.jpg)
What Is High Speed Machining?
The answer does not have to do with any particularspeed. It has to do with how that speed is used.
![Page 25: MODULE 01 High Speed Machines](https://reader030.vdocuments.us/reader030/viewer/2022020311/5695d35d1a28ab9b029dae6e/html5/thumbnails/25.jpg)
◦Very high tool rpm, small depths of cut and high feed rates
◦Mostly used in milling hard mold and die steels (hence term “hard milling”)
What is it? HSM
![Page 26: MODULE 01 High Speed Machines](https://reader030.vdocuments.us/reader030/viewer/2022020311/5695d35d1a28ab9b029dae6e/html5/thumbnails/26.jpg)
◦Maximizes overall productivity – fewer process steps, faster machining
◦Machining Mold and Dies made of very hard materials (P20, H13, D2, etc.
Tool or Mold steels), deep cavities and fine details typically require time
consuming EDM processes.
◦HSM produces high quality finish on milling machine – reduces need for
EDM electrodes, burning and hand finishing

Henry Ford (July 30, 1863 – April 7, 1947)
American industrialist, the founder of the Ford Motor Company.
Sponsor of the development of the assembly line technique of massproduction.
Although Ford did not invent the automobile or the assembly line,he developed and manufactured the first automobile that many middleclass Americans could afford.
In doing so, Ford converted the automobile from an expensivecuriosity into a practical conveyance that would profoundly impact thelandscape of the twentieth century.

Simulation..??
It can be defined as a process of developingmathematical models of a real system toevaluate the impact that some parametershave on a given output.
Advantages:◦Cost reduction and time saving
◦Complex systems can be evaluated
◦Visualization under variety of conditions
![Page 35: MODULE 01 High Speed Machines](https://reader030.vdocuments.us/reader030/viewer/2022020311/5695d35d1a28ab9b029dae6e/html5/thumbnails/35.jpg)
Types of Simulations:Discrete:◦ State of system changes only at ‘discrete event’ times.
◦ e.g. Customers arrive at a bank branch, trucks travel on a highwaynetwork
Continuous:◦ State of system represented by algebraic or differential equationswith variables that change continuously over time.
◦ e.g. Nuclear reactions, chemical process, ocean waves

Types of Simulations:Mixed:◦The system has discrete elements as well as continuous elements.
◦ e.g. Metal moulding and casting, ecosystems etc.
Dynamic:◦The system status changes over time. It requires that system performance with respect to time be taken into account.
◦ e.g. Speed of a vehicle, Revolutions per minute
