Computerized Numerical Control (CNC) – Skill Development Program:

The CNC Machining Program prepares students for a high-demand, entry-level position as a CNC machine operator or general machinist. CNC operators work in a variety of manufacturing environments and are trained to program, set-up, and operate a computer numerical control (CNC) machine, inspect parts, perform production runs and set-up jobs. Demand for CNC machine operators is continuously rising in manufacturing businesses.

 

The RNGPIT in collaboration with SETU foundation, Surat offers CNC training for students from various cadres like Degree engineering, Diploma Engineering, Bachelor of Vocation etc.

 

Course Objectives:

  • To understand the main features and working parts of CNC machines and accessories (2 axis machines to 5 axis machines including machining centers)

  • Understanding and minimizing the hazards associated with machining operations on CNC machines.

  • Understand the common terminologies used in CNC Programming like program number; part number and name; tool names; operation names; motion commands; tool change positions and commands; tool numbers and offset numbers; subprograms and canned cycles; tool nose radius compensation commands; spindle, feed rate and coolant commands etc.

  • Understand and effectively use the methods of checking quality of shaped components against required standards; impact of depth of cut on chatter, surface finish; range of materials used in common engineering applications and identify materials by their physical properties. 

  • Read and establish job requirements of raw material / component, dimensions, limits and tolerances, surface finish, shapes etc.

  • Report and rectify inconsistent information, conduct prelim checks on machines, extract and use information from engineering drawings, identify tools and suitable work holding devices. 

  • Carry out programming for CNC Machine: ensure that the program is efficient with commands for tool motions, spindle motions etc. in syntax corresponding to the machine and control system of the CNC machine.

  • Transmit and check the errors; handle the typical problems with the programming, loading and editing activities effectively.
