Mastercam CNC Programming Course: 2D and 3D Milling – London, 17–21 May 2027

Programme overview

Introduction:

Mastercam CNC programming course: 2D and 3D milling is a one-week course for CNC programmers, production engineers, tooling specialists, and machining supervisors, culminating in a CNC Milling Production Programming Package. Manufacturing units frequently face long cycle times, rapid tool wear, unpredicted machine collisions, and costly part scrapping from unverified toolpaths and inconsistent machining parameters. Nominees already interpret engineering drawings, configure basic workpiece offsets, and operate numerical control equipment, with instruction delivered through a technical lab. CoreConcept Training Center delivers this Mastercam CNC programming course: 2D and 3D milling to establish rigorous programming standards and cycle efficiency.

Course Objectives:

• Translate complex CAD model geometries into validated wireframe and surface machining features adhering to ASME Y14.5-2018 dimensioning conventions.
• Program high-efficiency 2D milling toolpaths using Mastercam Dynamic Mill strategies to control radial chip thinning and extend tool life.
• Generate multi-surface 3D roughing and semi-finishing toolpaths utilizing Mastercam OptiRough routines to accelerate bulk material removal.
• Apply 3D finishing strategies including scallop, equal scallop, and pencil milling to achieve specified surface finish tolerances.
• Configure post-processors and verify numeric code against ISO 6983 standards to prevent machine collisions across industrial CNC controllers.
• Compile a complete CNC Milling Production Programming Package comprising setup sheets, tooling lists, verified G-code, and backplot simulation reports.

Target Audience:

• CNC programming specialists responsible for converting engineering designs into production machine code and setting machining strategies
• Production machining engineers responsible for establishing cutting parameters, tooling selections, and process repeatability across milling centres

Conclusion:

Upon returning to the organisation, participants apply the CNC Milling Production Programming Package to standardise shop-floor execution across numerical control milling centres. Production managers and machining supervisors use this technical package to approve machining schedules, allocate spindle capacity, and verify cutting tool investments for new component production runs. Following the initial machining cycle, the engineering team must review actual component cycle times, cutter wear patterns, and coordinate measuring machine inspection reports against programmed models to refine feed rates and sustain long-term operational efficiency across machining operations.
