Application of GD&T on Technical Drawing by Using CMM


Course Objectives

Distinguish types of technical drawing and its application that is used as graphic communication.

  • Demonstrate proficiency in properly using the dimension components such as extrusion lines, dimension lines, leader lines, arrowheads, and so on, and application of the dimensioning techniques.
  • Understand the concept spatial visualization and demonstrate proficiency in applying of visualization techniques, especially the six views of the orthographic projection.
  • Understand the difference between first and third angle projection are used in orthographic projection.
  • Know how to prepare various types of section views that will help to illustrate the hidden views of an object in clearly and precisely, this will communicate more information about objects with complicated internal features than can illustrate in the drawing.
  • Define the concept of auxiliary views and its application that shows the true shape to the objects with inclined surface that are not always parallel to the regular planes of projection.
  • Explain the three main dimensioning systems in used such as the metric, decimal inches and fractional dimensioning.
  • Understand certain importance terms such as size is the overall dimensions are as specified, form is the shapes specified must have the correct geometrical form, fit which is two parts must mate as specified and function that is the product conforms to performance specification.
  • Understand the two terms are emphasized in GD&T; the reliability is the product performing its intended function under stated conditions without failure for given a period, and the interchangeability is defining the part able to replace without do any modification.
  • Understand product designers’ count on these geometric controls to provide design assurance that the product will have the appropriate fit, form, function, and/or reliability. Understand geometric tolerancing symbols are used to specify the functional relationship between or within part features and have specific rules about them that have a direct bearing on how the part must be inspected and produce.
  • Understand datum that is the starting point for the measurement and a specific description of the tolerance zone so that the observer can decide if the product is within or out of specification, and also the manufacture will produce the products are according to designer intention.
  • Understand a variety of inspection equipment, especially like coordinate measuring machine (CMM), and finding the appropriate measuring or gauging method that will properly evaluate the part feature being controlled.
  • Understand the contents and requirements of various types of the feature control frames, there are including multi-segment and composite.
  • It provides participants with the knowledge and skills such as the term used, the concepts of coordinate system and metrological requirement, the CMM application techniques and identifies various sources of error that affect measurements using a CMM.
  • Understand the functions of CMM that contain the information such as magnitude and direction of the elements, construction elements, datum, alignment, outcome products from function tasks and part programing that automatically evaluate the characteristics on a specified object.
  • Able to operate the CMM to set up part alignment, probing and construct features and using these features to produce the outcome such as coordinates position, lengths, diameters, angles and geometric variations.
  • Demonstrate proficiency on the measurement controlled by geometric tolerance such as form, orientation, location, runout and profile.
  • Distinguish the measurement methods among the cylindricity, total runout position and concentricity, and then evaluate the results.
  • Avoid any argument regarding measurement results due to competency in handling measurement process that follows the metrological requirements.
  • Increase interesting using CMM to obtain the measurement results as functions on product qualification because they understand the concepts and application of GD&T system that use to total control on the product quality.

Target Audience

Automotive, Aerospace, Engineering, Tooling, Fabrication, Casting, Mould maker, Medical devices manufacturer and all industries involving GD&T.

Designer & Drafting personnel, tool makers, machinist, engineers, inspectors, sale & marketing personnel and all others require to interpret or apply GD & T. It can serve as a refresher for experienced technicians; or it can be used in orientation for new hires.
This course will greatly help companies striving to high quality of product to fulfil the high technology and complexity of market demands.
* Participants must have basic knowledge of Technical Drawing and GD&T.
* Require at least one participant familiar with CMM to operate the machine.
