DETAILED AGENDA
Day 1
Introduction to CMM - CMM Basics; How do they work? Safety precautions; Why use a CMM? Quick review of probe heads and probing tech (touch, scan, laser, vision, etc.) ; Cleaning parts, probe tips, etc. ; System boot up procedure ; CMM basics and maintenance ; Understanding manual handboxes
Basic metrology Concepts - What is Metrology and measurement (NPL) ; Importance of measurements ; measurement uncertainty; CMM and Part influences; Environmental conditions; Measurement strategy; Fixturing and Orientation; Traceability; CMM calibration and interim checks; Programmer influences
Understanding CMM Programming - Programming Basics; Cartesian Coordinate System vs. Polar Coordinates; Right hand Rule; Vectors; Degrees of Freedom; Components of a Part Coordinate System (PCS); Primary; Secondary; Tertiary; Translation & Rotation; Alignment vs. Datums vs. PCS; Do all features make good datum features (thin, short, tiny, etc)?; Angles and angular convention
Day 2
Probes & Probe Calibration - A & B Angle Conventions; Explanation of Probe Calibration; Probe Compensation; Assembly of Probes, modules, extension, styli, etc; Size and Form tolerances for calibration; Number of points for probe calibration; Calibration schedule; Cleaning the stylus and other components
Simple Inspection - Measuring 2D & 3D Features; Manual measurement techniques; Proper probing; Location of points; Number of points; Text Prompts; Common mistakes; Measuring small or partial features
Understanding a PCS - Establishing the primary axis first; 3 Plane PCS; Plane Line Point PCS; A refined PCS
Good programming practice - Naming conventions; Features; Probes; Tolerances; Adding user Prompts; Formatting Code; Header; White Space; Comments; Subroutines; Logical grouping / Blocks; Program Header; Program Revision Control
Day 3
In Depth Analysis of Probing - Determining optimal stylus size; Probing direction (normal vs skewed); Determining optimal Touch Velocity; Choosing length of stylus & EW; Stylus materials
How do you know your program is providing correct results? - Determining repeatability of the program; Determining reproducibility; Determining the accuracy of the program; Correlation and acceptance standards; AS9100; ISO; Common Programming and Measurement Pitfalls
Settings - Proper use of CMM settings; Decimal Places; Feature algorithms
How do you know your CMM is providing correct results? - Probe Calibration results; Probe calibration correlation; Errors in probing and length (E0,MPE , PFTU,MPE) ; Advantages of single probe angle vs. multiple probe angles ; B89.4.10360-2 & ISO 10360; Interim checks ; Use of master part ; Use of artifact ; Monitoring/Tracking CMM performance and errors ; Use of temperature compensation ; CMM ; Probing ; Part ; Calibration Sphere certification ; CMM and/or probing warm up
Programming to standards - Are programs written to the standard indicated on the blueprint/cad model? How closely do the programs conform to the standard? ; Providing measurement methodology with results (algorithm, number of points, filters used, etc.)
