3. CNS means Computer Numerical Control. A Computer
Numerical Control is the automation of machine tools by
which we can draw different types of letter, picture provided
by a computer using software into it’s controller. This means
a computer converts the design into numbers which the
computer uses to control the cutting and shaping of the
material.The code used to program CNC machines is
generically called G-code. However,G-code instructions are
only part of the programming language. Specially G-codes
gives CNC machines the coordinates.
4. 1.Describe the development
of the machining centre.
2.Understand a basic CNS program for a machining centre.
3.Provide plotting operations as an alternative for traditional
manual operations done by manually operated machanism.
4.To developing a low cost automatic mini CNC machine for
PCB drawing and drilling.
5. 1.Actual industrial CNC milling:
It is planned to scale up the prototype CNC machine in terms of
size, use more powerful motors, strengthen the frame and
worktable with material like aluminum and augment the CNC
control software with software for stimulation ahead of actual
run. The implementation of 3D technology to the same hardware.
Abstract is going for printing of 3D models.

day,365 days a year and only need to be switched off for
Occasional maintenance machines are programmed with a
design which can be there manufactured hundreds or even
thousands of times. Each manufactured product will be exactly
the same. The programs produce a computer file that is
interpreted to operate a particular machine by use of post
processor, and then loaded into CNC machines for production.
Using small machine tools fabricate small scale parts can
provide both flexibility and efficiency in manufacturing
approaches and reduce capital cost, which is beneficial for
small business owners.
