REPORT ON One Day workshop on CNC Programing
A One Day workshop on “CNC Programming” by Er.Neeraj , an industrial expert from GNA gears private. Ltd. Hoshiarpur was organized by the Department of Mechanical Engineering on 11th Sept., 2018
Department of Mechanical Engineering arranged skill development Workshop on CNC programming for mechanical engineering students. Now in a day’s use of CNC Machine in all industries is increase day by day so this course introduces the concepts and capabilities of computer numerical control machine tools. Topics include Introduction about CNC technologies. Part Programming, Geometric dimensioning and Tolerances, setup CNC machine for operation and basic practice on CNC machine in context with industrial applications gives real industrial knowledge to the attendees. With completion of this course students should be able to operate CNC machine as well as able to program any industrial component.
After Completion of this introductory session start with all terminology related CNC machine is explained to students so they will understand all the parameters of CNC part programming easily. The CNC part programming is based on coding so all coding system explain by the respective faculty to student and so that they can understand brief of programming. After this session conduct another session for cutting parameter, tool selection and insert selection. There are many parameters for cutting which is feed, speed and depth of cut. All parameters consider for CNC machine which is used in manufacturing process. There are different cutting tool which is use differently for straight turning, taper turning, thread cutting etc. processes.
After completion of all theoretical knowledge about CNC machine start with actual part programming which is used for manufacturing in CNC machine.
There are many codes used for CNC machine in which G code, M code, N Code, X,Y,Z code, S code etc. which is used for part programming.
N -Block number -specifies the start of the block
G -Preparatory functions
M -Miscellaneous functions
X -X-axis coordinate
Z -Z-axis coordinate
I -X-axis location of arc center
K -Z-axis location of arc center
R -Radius of arc
S -Spindle speed or Cutting speed
F -Feed rate
T -Tool number
CNC machine basically work on thumb rule and for axis designation.
