Course Preamble

The Mechanical Industry is increasingly finding applications in all sectors of the economy and thus is accepted as a key enabler in development of our country. The current growth trend and its existing contribution to the global mechanical industry indicates that the share of Design and Manufacturing Industry in India, in terms of output and employment, has the potential to grow manifolds, driven by its emergence in the global manufacturing value chain.
In order to create a conducive environment for manufacture of high technology, and other high tech mechanical products, attract global investments as well as bridge the viability gap due to lack of adequate infrastructure and ecosystem, Government of India has announced number of initiatives in the country. To this aspect, there is also a need to ensure availability of trained human resources for this sector in order to sustain growth and to achieve the targets set for this sector.

Course Objective

The Certificate Program on CNC Machines and NC Part Programing aims to enable Mechanical/Production engineers/Diploma holders or
working engineers in mechanical industries to learn programming and operation of CNC Machines. This is offered to bridge the major gap in competencies required to program & operate CNC machines. This course enables students to have industry oriented training on CNC machines.

Course Outcome

The participants will be able to understand:

  •  Fundamentals of NC/CNC
  •  NC Part Programming
  •  Conventional versus CNC Machine
  •  Tooling for NC/CNC
  •  Chucking, Turning Centres and Machining Centres
  •  Maintenance and Trouble Shooting of CNC Machine Tools

Course Structure

Course Contents

Fundamentals of NC/CNC

The term numerical control is a widely accepted and commonly used term in the machine tool industry. Numerical control enables an operator to communicate with the machine tools through a series of numbers and symbols, called part program. This chapter deals with the basic understanding of Numerical Control machine tools and the co-ordinate systems adopted for these machines

NC Part Programming

Numerical control (NC) operates machine by sending a series of coded instructions consisting of alphabet letters, numbers, and symbols in language that machine control unit (MCU) can understand. The coded instructions or commands are listed in a logical sequence to have a machine tool to perform a specific task or a series of tasks in  order to produce a machined part. Hence the NC machine user must have knowledge about NC the part programming in order produce a finished part by using NC or CNC machine.

This module covers NC part programming in detailed manner and gives more information about special machining cycles (e.g. canned cycles for all types of machining).

Conventional versus CNC Machine

This module deals with the comparison and benefits of NC/CNC machine tools over conventional machines. It briefly describes the design considerations, constructional details of NC machine tools, DNC, CNC, and the advantages and disadvantages CNC over other machines

Tooling for NC/CNC

Increased manufacturing speed and less tolerance errors has spawned the need for more efficient tool management. It's important to know where the tool is, how long it will last, and what the offsets are. In the past, operators kept track of these operating details manually. This module describes about cutting tool theory, Turning and milling tools, adaptive control and some latest developments in CNC tooling field like telltale tools etc

Chucking and Turning Centers

Numerical controlled (NC) lathes had a very slow start in manufacturing. Studies during the 1960s indicated that 40 percent of all metal cutting operations were performed on lathes, yet NC lathe accounted for only 7.4 percent of the total NC sales at that time. These lathes were standard engine lathes had been retrofitted for NC. The term retrofit means fitting control systems and other required NC gear to a conventional piece of equipment that was not originally designed for NC. These NC lathes were a significant improvement over the conventional and tracer lathes being used at that time. They were capable of making contour cuts by controlling the coordinated motion of the cross slide and the carriage. Thread cutting was made possible by the automatic synchronization of the spindle
RPM and the travel of the carriage.

Machining Centres

Machining centers are evolved from the need to be able to perform a variety of operations and machining sequences on a workpiece on a single machine in one set-up. Many parts require machining on several machines and may spend weeks on the shop floor waiting and moving from one machine to other machine.
Operations such as milling, contouring, drilling, counter boring, boring, spot facing, and tapping can now be performed on machining centers in any sequence and require only one set-up. Machining centers equipped with automatic tool changers, automatic pallet changers rotary tables, and rotary work heads make this a very versatile machining while reducing the operator intervention during the cutting cycle

Maintenance and Trouble Shooting of CNC Machine Tools

Maintenance is war. Your enemies are the triumvirate of breakdown, deterioration, and all types of unplanned events. Your soldiers are the maintenance department and as many civilians as you can recruit. The civilians you protect are production workers, office workers, drivers, and all the other users of your organization’s assets. This module gives you an overview about types of maintenance, CNC system & mechanical maintenance aspects
