Learning Center to hold CNC machining classes

Posted: Friday, February 14, 2020

The Huntington County Community Learning Center will hold courses to introduce the theory of programming Computerized Numerical Controls (CNC) for industrial metal working machines. Participants will study terminology of coordinates, cutter paths, angle cutting and linear/circular interpolation.

Related machining practices in milling and turning will be covered, and shop mathematics will be introduced and applied for fractions/decimals, metrics, geometry, calculating formulas and trigonometry. This course also incorporates blueprint reading for interpreting working drawings used in the trade.

Participants will have hands-on training and demonstrations on CNC machining equipment while developing competencies in both the operation and basic programming of equipment controls.

Some learning objectives are: demonstrate competencies with shop math skills necessary for calculating angles, tapers, cutting speeds, feeds, gear ratios, etc.; the ability to read and interpret blueprint specifications/symbols common to a machine shop environment; learn proper use and care for precision measuring equipment and basic layout techniques; demonstrate proficiencies with common metal cutting practices; understand terms and definitions related to machine tool operation; learn common formulas for calculating machining feeds and speeds; learn to write test programs using absolute and incremental point definitions, and cartesian and polar coordinates; learn to program “G” code preparatory functions, and miscellaneous functions in “M code; demonstrate competencies in tool offsets and basic program writing using subroutines; demonstrate competencies programming setup and operations of tooling applications for CNC machining and demonstrate competencies needed for producing or simulating the production of an assigned project or machined part sample relative to learning equipment.

Upon successful completion of this course, participants will test for the NIMS Mill Operator and NIMS Lathe Operator certifications. Students earning those certifications may qualify to receive up to three credit hours toward Ivy Tech Community College Northeast courses. Participants must apply and be accepted into an applicable degree program as well as meet any required prerequisites prior to college credit being issued for this course.

This program qualifies for the State of Indiana Workforce Ready Grant. Eligibility includes state residency, a high school diploma (or equivalent) and no degree past high school. All participants must apply to be accepted into the class. For more information, including non-eligible students, contact Scott Wilson at
