ADVANCED CNC MACHINING TECHNITION : Year wise Trade Overview
FIRST YEAR: Safety being the most important thing in all the industries now a day is covered in the first year to start with. The input in this trade is always the drawing, so the students are taught to read Industrial drawings, concept of GD & T and ISO Tolerances. The students are also introduced to latest trends and other advanced technologies. The students are oriented with the computer aided machining concept and given working knowledge of types of cutting tools & selection criteria. The students are also imparted the knowledge of materials used in industry and their properties & their impact on cutting tool life. The students are trained in use of different measuring instruments used in the industry and selection of appropriate measuring instrument based on the tolerance as per component drawing.
The practical training starts with the standard operating practices of the CNC Machines based on the operating manual like referencing, checking the condition of tools, spindle orientation, checking the daily check points etc. The students are taught the basic G-codes and M-codes used for programing the CNC Turning Center, making of program and running it in various modes and optimizing the program for idle movement for cycle time.
SECOND YEAR: In the second year, the students are taught the operation and programing of Vertical Machining Center with ATC and 4th axis.
The practical training starts with the standard operating practices of the VMC based on the operating manual like referencing, checking the condition of tools, spindle orientation, checking the daily check points etc. The students are taught the basic G-codes and M-codes used for programing the Vertical Machining Center, making of program and running it in various modes and optimizing the program for idle movement for cycle time.Alsooperatingandprogrammingof4&5axis machine, tool indexing, program creation & simulation.
