CNC operators, developing machinists and manufacturing technicians
CNC Machinist
A machining pathway connecting drawings and metrology to setup, offsets, G-code, cutting tools, workholding and first-piece verification.
Role learning outcomes
A practical curriculum target for the role.
- Read the engineering requirements that control a machining task.
- Prepare and verify a CNC setup within approved procedures.
- Interpret program, work-offset and tool-offset relationships.
- Use measurement evidence to confirm first-piece and ongoing process results.
Possible evidence in a workplace program
- • Setup observation
- • First-piece inspection records
- • Tool and offset verification
- • Knowledge assessments
Employer qualification, machine authorization and regulatory requirements remain separate from Industrial Skillset learning records.
Foundation
Build the technical language and work context needed before role-specific depth.
Foundational
Engineering Drawings and Blueprints
Learn how industrial drawings communicate geometry, dimensions, tolerances, materials, finishes, assembly relationships and revision-controlled requirements.
Foundational
Metrology: Calipers, Micrometers and Indicators
Develop correct measurement habits with common precision instruments and understand resolution, repeatability, calibration and measurement technique.
Foundational
Manual Machining Fundamentals
Understand the basic operating principles of manual lathes, mills, drills and grinders, including workholding, cutting tools, speed/feed concepts and measurement.
Core role knowledge
The principal equipment, methods and controls most directly connected to the role.
Intermediate
CNC Machining Centers
Study the architecture and workflow of CNC milling and turning systems from program and setup through offsets, tool management, machining and inspection.
Intermediate
G-Code, M-Code and CNC Program Structure
Understand common CNC program structure, motion commands, coordinate modes, spindle and coolant functions, offsets and safe program-reading practices.
Intermediate
CNC Probing, Work Offsets and Tool Offsets
Study how machine probing, work coordinate systems and tool offsets support repeatable CNC setup, part location and process verification.
Intermediate
Cutting Tools, Feeds and Speeds
Understand how tool material, geometry, cutting speed, feed, depth of cut and workpiece material interact to influence productivity, tool life and surface condition.
Intermediate
Workholding, Fixtures and Jigs
Learn how vises, chucks, clamps, locators, fixtures and jigs establish part position and resist process forces while supporting repeatability.
Intermediate
Turning Operations and Lathe Process Fundamentals
Study common turning operations, tool geometry, workholding and process variables used to produce cylindrical features.
Intermediate
Milling Operations and Machining Strategy
Understand common milling operations, cutter selection, toolpath concepts and workholding relationships used to create prismatic features.
Advanced & quality context
Deeper technical, quality or systems knowledge that strengthens independent problem recognition and cross-functional work.
Intermediate
Geometric Dimensioning and Tolerancing (GD&T)
Understand how GD&T communicates allowable geometric variation using datums, feature-control frames and standardized controls for form, orientation, location and runout.
Intermediate
Surface Finish and Profilometry
Understand how surface texture is specified, measured and interpreted using roughness parameters and profilometry concepts.
Intermediate
Precision Grinding Fundamentals
Understand grinding-wheel selection, dressing, workholding and process variables that control geometry, thermal damage and surface finish.
Intermediate
Coordinate Measuring Machines (CMMs)
Understand CMM fundamentals, probing, alignment, datum establishment and how inspection programs translate drawing requirements into measured results.
Intermediate
First Article Inspection (FAI)
Understand the purpose of first article inspection as a structured verification that manufacturing planning and the produced article satisfy defined engineering requirements.
Intermediate
Statistical Process Control (SPC)
Understand how process data can be used to distinguish routine variation from signals that warrant investigation, supporting stable and capable production.
