Since the Last edition oi this catalogue ol Surveying and Matl tical Instruments was issued, many improvements both optical and mechanical sli have been incorporated in various instruments, as experience 1 them to be advantageous. The long business relations which the firm of J. H. Steward, Ltd., has enjoyed with members of the Surveying and Allied Professions, and as contractors to H.M. Government, has put within their reach facilities for gaining practical experience which could not be otherwise obtained. Opportunity is here t.iken of thanking those clients who have made valuable suggestions and have so generously placed at our disposal the results of their practical experience. YVi have every facility in our Repair Department for r< iring any make oi Surveying and other Scientific Instruments, and also for carrying out experimental work and for constructing instruments to 3] I specifica- t ion. We would draw attention to other departments of the business oi which further d< tails will be found at the end of this catalogue.

  • CHAPTER 6 Technical Drawing Tools Based on Technical Graphics Communication by Bertoline, Et Al Dr Simin Nasseri, Southern Polytechnic State University
    CHAPTER 6 Technical Drawing Tools Based on Technical Graphics Communication by Bertoline, et al Dr Simin Nasseri, Southern Polytechnic State University OBJECTIVES After completing this chapter, you will be able to: 1. Identify the important parts of a CAD system used to create technical drawings. 2. Define the important terms related to CAD systems. 3. Identify the important traditional tools used to create technical drawings. 4. Define the important terms related to traditional tools. 5. Use traditional tools and CAD to draw lines, circles, arcs, and curves. 6. Use scales, dividers, and CAD to measure and scale drawings. 7. Identify standard metric, U.S., and architectural drawing sheet sizes. 8. Identify standard pencil grades, and identify those most commonly used for technical drawings. 9. Identify the types and thicknesses of the various lines in the alphabet of lines. 10. Use traditional tools and CAD to erase parts of a drawing. INTRODUCTION Just as the graphics language has evolved over the years into a sophisticated set of standards and conventions, so have the tools used to graphically communicate technical ideas. Tools are used to produce three basic types of drawings: freehand sketches, instrument drawings, and computer drawings and models. 6.1 TECHNICAL DRAWING TOOLS Computer-aided design/drafting (CAD) is computer software and related computer hardware that supplements or replaces traditional hand tools in creating models and technical drawings. Engineers use computer-aided design/computer-aided manufacturing (CAD/CAM) in the design and production processes. 6.2 COMPUTER-AIDED DRAWING TOOLS A CAD system consists of hardware devices used in combination with specific software.

  • Electronic Theodolites, Electronic Tacheometers, Total Stations and Data Collectors
    ELECTRONIC THEODOLITES, ELECTRONIC TACHEOMETERS, TOTAL STATIONS & DATA COLLECTORS Electronic theodolites operate in a manner similar to that of optical theodolites or even vernier transits. Angle readouts are to 1 second, with accuracies from 0.5 to 10 seconds; digital readouts (LED or LCD) eliminate the guessing and interpolation of circle and micrometer settings associated with scale and micrometer theodolites. Electronic theodolites have zero-set buttons for quick instrument orientation after the backsight has been set; horizontal angles can be turned left or right, and repeat-angle averaging is available on some models. Some models also include horizontal and vertical collimation corrections, and vertical circle readings referenced to zenith, horizon, or percent slope format. The most significant characteristic of electronic theodolites is their ability to be interfaced electronically to data collectors and to computers, permitting a quick, error-free transfer of field data to the computer. Electronic tachometers (ETI) combine electronic theodolites with EDM instruments both of which are interfaced to a data collector. In this configuration it is called a total station. These electronic tachometers can read and record horizontal and vertical angles together with slope distances. The microprocessors in the ETI can perform a variety of mathematical operations (e.g., averaging multiple angle measurements; averaging multiple distance measurements; X, Y, Z coordinate determination; remote object elevations (heights of sighted features); distances between remote points; adjustments for atmospheric conditions; and so on. In addition, attribute data such as point numbers, point codes, and comments can be included with the recorded field measurements. The data collector is usually a hand-held device connected by cable to the tachometer, although some manufacturers have the data collector included as an integral component of the instrument.

PUB DATE Oct 83 NOTE 325p. PUB TYPE Guides Non-Classroom Use (055 EDRS PRICE MF01/PC13 Plug Postage. DESCRIPTORS *Behavioral Objectives; *Equipment; *Evaluation Criteria; Hand Tools; Job Analysis; Machinery Industry; *Machine Tool Operators; Machine'Tools; *Machinists; Metal Working; *Occupational Information; Performance Factors; Performance Tests; Postsecondary Education; Secondary Education; Specifications; Task Analysis; Vocational Education ABSTRACT This catalog provides performance objectives, tasks, standards, and performance guides associated with current occupational information relating to the job content of machinists, specifically tool grinder operators, production lathe operators, and production screw machine operators. The catalog if; comprised of 262 performance objectives, tool and equipment lists, and performance guides that were prepared from job-related task statements from the occupational inventory. Each performance objective contains the condition under which the student will perform the objective, the performance required of the worker in the job environment, and a job-relevant standard for measuring successful performance of the objective. The source of the standard for each objective is - documented. Tha tool and equipment list includes the required tools and equipment for completing the performance guides. 'Accessories included are the necessary tools and machinery parts used with a basic machine. The performance guides that accompany the tasks provide proceducal steps identified as subordinate to task performance.
