GAGE REPEATABILITY AND REPRODUCIBILITY STUDIES Introduction: R&R Studies analyze the variation of measurements of a gage (repeatability) and the variation of measurements by operators (reproducibility). Scope: Why perform Gage R&R Studies · They help to avoid significant measurement error on product acceptance and on control charts and/or process capability studies. · They provide criteria for accepting new measuring equipment. · Comparisons between different measuring devices can be made more effectively. · They help to evaluate deficient gages as opposed to incapable/out-of-control processes. · They provide validity for statistical control and capability methods used in the process. · They improve equipment maintenance, selection, calibration, and use. · They improve observer's training and skill (as necessary). When Should Gage R&R Studies be performed The most effective time to perform gage R&R studies is before the gage is used to gather data or inspect products. In this preventative mode, problems that are associated with taking data, charting, capability analysis, acceptance errors, and so on are avoided because the measurement system that fails a gage R&R study is corrected before data are collected. Along with the prevention mode, however, comes the task of performing a variety of studies before data collection can begin. Gage R&R is a proven analysis method for measuring the capability of the measurement system and isolating the primary source(s) of measurement errors (observer or instrument). Using gage R&R, the intent is to:(1) identify the measurement processes that require improvement, (2) identify the source of measurement errors (observer or equipment), and (3) correct the error. Training Objectives · To understand the issues involved in repeatability and reproducibility (R&R) studies · To learn how to estimate the repeatability and reproducibility in a measurement process · To master the available statistical and graphical tools for summarizing and presenting study results · To make a decision on the acceptance of the measurement system · Exercises are given to make the studies more effective. Who Should Attend · Laboratory, production line and quality control personnel, anyone who must determine the accuracy and precision of gages, instruments and operators in a measurement process. · Participants must be comfortable using a scientific calculator and simple algebra formulas.

STATISTICAL PROCESS CONTROL Introduction Statistical Process Control (SPC) is a method of monitoring, controlling and, ideally, improving a process through statistical analysis. Its four basic steps include measuring the process, eliminating variances in the process to make it consistent, monitoring the process, and improving the process to its best target value. SPC will not improve a poorly designed product's reliability, but can be used to maintain the consistency of how the product is made and, therefore, of the manufactured product itself and its as-designed reliability. Properly applied statistical control can prevent problems and lead to: Continuous Improvement in product quality; improved productivity and reduced overtime, Reduced rejection, rectification, test and inspection costs. Reduce the occurrences of defective goods getting past the goods inwards stage. Scope Basic Mathematic Concepts (Statistical & Probabilities), SPC Tools, Variable Control Charts, Attribute Control Charts, Interpretation of Control Chart, Process Capability Study. We include case studies to make the studies more effective. Training Objective Why do we need SPC? If your company, division, or unit is to continue providing jobs, you will need to use SPC. Survival of the company will depend on SPC because competitors who use SPC will be able to make product or provide services better and faster. But your company can do the same and do it better. Your company will not only survive but it will grow. Who Should Attend Quality Engineers, Technicians, Managers, Engineers, Engineering Technicians, Manufacturing Engineers, Production Managers, Supervisors and personnel who wish to introduce and employ SPC techniques. Participants must be comfortable using a scientific calculator and simple algebra formulas.

INTERPRETATION OF TECHNICAL DRAWING 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 understand the meaning of the lines and symbols drawn on the page; and to make the mental conversion of these two dimensional drawings (plans and elevations) into a three dimensional (3-D) reality. Scope Computer Assisted Draughting (CAD) is getting more popular in the engineering industries but this focuses on techniques of drawing, not on how to interpret existing drawings. This course covers four main areas as follow: (a) Technical Drawings- Common terminology, drawing sheet, projection views, angle projection, lines, sectional views, auxiliary view, dimensioning and notation, allowances and fits, chamfers, rounds and fillets, threads and gears (b) (c) Dimensional Metrology- Introduction to Metrology, common dimensional measurement instruments and Measurement system. Geometric Dimensioning & Tolerancing ­ Last square estimation method, Symbols, Rules, Standards, Projected zone, Tangent zone, Free-State variation, Restrained features & Interpreting of GD&T. Case study

GEOMETRIC DIMENSIONING AND TOLERANCING Introduction Geometric Dimensioning and Tolerancing (GD&T) is a universal language of symbols, GD&T symbols allow a Design Engineer to precisely and logically describe part features in a way they can be accurately manufactured and inspected. Dimensioning and Tolerancing and Geometric Dimensioning and Tolerancing specifications are used as follows: Dimensioning specifications define the nominal, as-modeled or as-intended geometry. Tolerancing specifications define the allowable variation for the form and possibly the size of individual features, and the allowable variation in orientation and location between features. GD&T is used most often on engineering drawings. There are several standards available world-wide that describe the symbols and define the rules used in GD&T. One such standard is ASME Y14.5M-1994. There are seven shapes, called geometric elements, used to define a part and its features. The shapes are: point, line, plane, circle, cylinder, cone and sphere. There are also certain geometric characteristics that determine the condition of parts and the relationship of features. The main purpose of GD&T is to ensure, · size - the overall dimensions are as specified · form - the shapes specified must have the correct geometrical form · fit - two parts must mate as specified · function - the product conforms to performance specification Who Should Attend Designer, engineers, quality, manufacturing, inspection and all others require to interpret or apply GD & T

(PRACTICAL DIMENSIONAL METROLOGY) COORDINATE MEASURING MACHINE ­ Technical Drawings, Geometric Dimensioning & Tolerancing (Usage & Application) 4 Days Training Course Code : D4-EN02-L1-R041

The four days training will be inclusive of theoretical and hands on activities. TRAINING OBJECTIVE To enhance engineers and technician knowledge on concept of measurement systems and hands on technical skill by operating CMM for measuring parts more effective and confident with measurement results. To ensure the confident of measurement results, the instruments must send for calibration and the operators must equip with sufficient knowledge and technical skill through technical training. Technical Drawing- The mark of a good technical drawing contains all of the information needed by individuals for converting the idea or concern into reality. The conversion process may involve manufacturing, assembly, construction, or fabrication. Regardless of the process involved, a good technical drawing allows the conversion process to proceed without having to ask designers or drafters for additional information or classification. SCOPE 1. 2. Concept of measurements. Technical Drawing ­ cover engineering drawing, geometric dimensioning and tolerancing (form, orientation, positioning, runout, modifier, datum and profile) and application of design drafting such as screws and gears. Hands on CMM Basic Measurement: measure elements (point, line circle, sphere, cylinder, cone and torus), length and angle. Advance Measurement : Special tasks, tolerancing measurements, part programming.
