COORDINATE MEASURING MACHINE CONCEPTS DURATION: 1 DAY; TIME SCHEDULE Time - 9:00am to 5:00pm Break - 10:15am to 10.30am and 3:15pm to 3:30pm Lunch - 1:00pm to 2:00pm INTRODUCTION The ability to read and interpret technical drawings is important in a large number of trades and professions, from bricklaying to engineering. Essentially, two skills are required to figure out this drawing. First is to understand the meaning of the lines and symbols drawn on the page; and second is to make the mental conversion of these two-dimensional drawings (plans and elevations) into a three dimensional (3D) reality. Dimensioning is the process of defining the size, form and location of geometric features, whereas tolerance is defining the allowable variation for the form and the size of individual features, and the orientation and location between those features. The combination of these two terms become “Geometric Dimensioning and Tolerance” abbreviated as GD&T. GD&T is a system for defining and communicating engineering tolerances. It uses a symbolic language on engineering drawings, thus GD&T is an effective communication tool for designer or customer to fulfil their intended product with criteria such as fit, form, function and reliability. With the GD&T, the manufacturer has a direct bearing on manufacturing the products, and then the inspector has a complete and doubtless set of specification to ensure these products fulfil the requirements. Many companies around the world use the GD&T. This is because GD&T is content with the symbols, rules, vocabulary, and mathematical definition and standard in order to transfer the intended design to others easily. With the standardized and mathematized of GD&T, anyone who knows the Standard will understand the drawing requirements. There are many standards to define the GD&T. Over time, complexities in manufacturing increased, all the standards became almost in line due the focus toward the same objective need for interchangeability of parts and assemblies manufactured around the world being brought together in an assembly plant that makes automobiles, tractors, airplanes, televisions, projectors, spacecraft, and so on. The standardized GD&T is a proven system to improve communications, control, and productivity in manufacturing throughout the world. This is because the GD&T is a complete specification of design requirements with symbols. These symbols allow the designer to specify maximum tolerances for parts that must assemble with other parts, and ensure the interchangeability of parts. This will increase productivity thus improve the product quality in terms of cost, time and functionality. The technical drawing with the GD&T system will make simple and complete requirements; it can be easily understood by anybody, but how can we verify the product according to these requirements? The coordinate measuring machine is one of the useful measuring equipment to overcome these problems. Coordinate measuring machine, abbreviated as CMM, are commonly used to measure three dimension measurements. CMMS were originally designed to suite the demand of the production rate and complexity of the product, It can be very time consuming and costly for an inspector to go into a detailed layout of 1|P a g e

most products that are produced on a numerically controlled machine. These products are usually with many features that must be inspected for position with reference to datum’s, planes, or surfaces. The person who makes the measurement is called an observer. The observer needs to be familiar with the measurement methods and the measurement software in CMM, and understanding the geometric dimensioning and tolerance and the rules about them. If the observer demonstrates this proficiency, then it can make the measurement fast and complete which will be able to fulfil the production demands. BENEFITS Upon completion of this program, participants will be able to: 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 the application of visualization techniques, especially the six views of the orthographic projection. Understand the difference between first and third angle projection which 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 clearly and precisely, which will communicate more information about objects with complicated internal features than can be illustrated 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 important terms such as size form and fit Understand the two terms emphasized in GD&T; the reliability is the product performing its intended function under stated conditions without failure for a given period, and the interchangeability is defining the part able to replace without 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 tolerance symbols used to specify the functional relationship between or within part features that have specific rules about them that have a direct bearing on how the part must be inspected and produced. Understand that datum 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’s intention. Understand a variety of inspection equipment, especially 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, including multi-segment and composite. Be provided with the knowledge and skills such as the terms used, the concepts of coordinate system and metrological requirement, the CMM application techniques and various sources of error that affect measurements using a CMM Understand the functions of CMM that contain 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. Operate the CMM to set up part alignment, probing and construct features and be able to use these features to produce the outcome such as coordinates position, lengths, diameters, angles and geometric variations. 2|P a g e

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 interest 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.
