Technical Skills Training

Computer Numerical Control l 

This course will provide an introduction to the preparation of Computer Numerical Control (CNC) machine code. The major mathematical and computer concepts needed for selected CNC machining tools are also introduced. Topics include:

• Cartesian and polar coordinate systems
• binary, ASCII, and EIA data encoding
• program preparation hardware and software
• linear and circular interpolation
• CNC milling

Computer Numerical Control ll  

This course builds upon the skills acquired in CNC l in developing more complex Computer Numerical Control (CNC) machine code.  Skills for angular cuts and circular cuts not parallel to a machine axis are developed.  2 1/2 axis methods, plane selection, and multiple tools are covered as well.  Topics include:

• simultaneous axis control
• cutter compensation
• tool magazines and tool attributes
• canned functions
• CNC turning

Machine Tool Introduction 

This focus of this course is the set up and operation of manual lathes and milling machines. It is designed to introduce the participant to the principles of machine tool operation in preparation for further training as CNC machine tool operators. Topics include:

• machine tool safety
• performance and selection of cutting tools
• planning machine tool operations
• set up and operation of vertical milling machines
• set up and operation of engine lathes

Math ll – Algebra for Machining 

This course is an introduction to algebraic concepts, including equality, unknowns, and solving for unknowns in formulas having multiple operations. Topics include:

• algebraic equations of the first degree
• unit measure conversions
• graphing algebraic formulas
• percentage calculations, ratio, and proportion

Math lll – Geometry for Machining    

An introductory course in qualitative geometry and visual interpretation.  The geometric elements discussed will include plans, angles, arcs, triangles and selected polygons.  The treatment of topics will focus on geometric properties and relationships encountered in blueprint reading and interpretation, part inspection, machine tool operation and CNC programming

Math lV – Trigonometry for Machining  

This course will provide an introduction to basic trigonometric concepts. Right triangle and oblique triangle trigonometry and the difference between them are also covered, along with trade-related applications of all topics. Topics include:

• sine, cosine, and tangent triangle calculations
• right triangle and oblique triangle trigonometry
• basic machine shop and CNC trigonometry uses
• identification of points in the plane using the solution of triangles
