Jack screw on the bottom of the bracket can be used to micro adjust the bracket position. (2) Abrasives This kit contains a premium coarse P80 ceramic oxide abrasive from Norton. This should be used to shape and sharpen tools. It is a very fast, yet cool, cutting abrasive and will shape or sharpen a tool very quickly. Once your tools are shaped to your desired geometry, your standard Work Sharp 3000 abrasive kit (P120, P400, P1000, 3600) will keep them sharp. Abrasive Kit contains: The Tool Bar has two primary positions P120 Grit: Intended for roughing, shaping and sharpening. (A and B) but is infinitely adjustable to P400 Grit: Intended for sharpening and edge refinement. meet your specific tool sharpening P1000 Grit: Intended for sharpening and edge refinement. needs. 3600 Grit: Intended for honing and polishing. Reference the Cast Line in the vertical (3) Tips and Techniques rod to set A or B position. Heat Control: Position A Be aware of your tool’s temperature to avoid burning the steel. Monitor the tool’s heat with your fingers. 150° is too hot to touch. Steel is not affected until 400°. If a tool becomes too hot, allow it to air cool or place it in a cup of water. Changing the grinding point on the wheel can help control heat. The wheel speed at the outer edge is faster (hotter) than the center of the wheel (cooler). Micro Adjust: Position B Cast Line You can micro adjust your height setting to acheive nearly any specific angle you desire (One full revolution is equivalent to .080 inches or +/- 2.5° at bevel angle). This makes it faster and easier to match the existing angle already sharpened onto your tool. This micro adjust nut will also hold the height (H) setting for you if you need to loosen the tool bar securing knob to swing the tool rest out of the way. (4) Set Up Fixture TSO B B H3 The Set Up Fixture helps set your STICKOUT TOOL H2 Tool Stick Out (TSO) and bar Height H1 2 3 1 (H). These two settings determine TOOL STICKOUT A the angle sharpened onto the tool. TSO A Setting the Tool Stick Out (TSO) There are two TSO settings (A and B). Reference the specific tool sharpening chart in this guide to determine which jig is needed, and which angle you desire. TSO B The chart will determine the TSO setting you will need to use. TSO A Setting the Tool Bar Height (H) There are three height (H) settings for sharpening your tools. When referencing the sharpening charts in this guide (Page 10, 15), the bar height is not limited to those heights and can be adjusted to any height needed. To create a standard, repeatable angle, reference the tool sharpening charts Tip: Tool Bar Height can also be H1 H3 set by placing the tool into the appropriate jig and adjusting the tool bar height until the tool bevel lays flat on the abrasive wheel. (5) Freehand Topside The tool bar can be placed at various positions and heights for topside freehand sharpening. A Set the tool bar to desired height and orientation to the grinding wheel. B Set the tool stick out on tool rest so the bevel angle matches that of your tool. When holding the tool, your hand (fingers) can be used to create a tool stop against the tool bar while sharpening. Tip: You can also scribe or mark a line onto your tool to identify the Tool Stick Out and record the Height setting for repeatable future sharpenings. (6) Freehand Underside The Tool Bar can be placed under the grinding wheel on the back side of the machine. This provides a stable tool rest for improved precision. When sharpening curved tools, use the Edge-Vision® slotted wheel see through wheel and abrasives. Edge-Vision® Slotted Wheel (7) Data Chart Use this data chart to record your sharpening set ups on various tools to increase repeatability and reduce your set up time. TSO H TBP: (A or B) Tool Name Tool Stick Out Height Tool Bar Position Notes Tip: Use a Black Marker when re-sharpening an existing angle onto a tool. Color the bevel to be sharpened then set up the tool (with or without jig) and Tool Bar so the bevel lays flat on the abrasive wheel. Turn the wheel by hand one half revolution. If black marker is removed at the heel of the bevel, use Micro-Adjust Knob to raise the Tool Bar. If black marker is evenly removed, your set up is perfect. If marker is removed only at the cutting edge, use Micro-Adjust Nut to lower the Tool Bar. Repeat until desired grind pattern and Tool Bar Height is achieved. (8) Tool Rest Jig Tormek® SVD-100 Tip: Reference Tormek® instructions for more detail on jig set up and use. Sharpening Scrapers: A• Mount tool bar in either ‘A’ or ‘B’ position. Position A - best for angles less than 70° Position B - best for angles between 70° and 90° B• Mount and clamp the Tool Rest onto the Tool Bar. C• Set the bar height (H) so tool rest is ¼” above the wheel. D• Place your scraper firmly onto the tool rest so the tip is on the abrasive disk. E• Adjust the Tool Rest angle so the scraper bevel is flat on the abrasive. F• Tighten the Tool Rest Knob to secure the chosen angle. Or set the angle desired for your scraper by using a protractor to measure the angle between the abrasive and Tool Rest. G• Use the coarse P80 grit abrasive for the fastest results and best burr formation.

  • Chapter 1 Jigs and Fixtures
    PQ726-0967G-P01[01-14].qxd 1/16/04 5:39 PM Page 1 Quark05 Quark05:BOOKS:PQ JOBS:PQ726 Miller(4) Chapter 1 Jigs and Fixtures Jigs and fixtures are devices used to facilitate production work, making interchangeable pieces of work possible at a savings in cost of production. Both terms are frequently used incorrectly in shops. A jig is a guiding device and a fixture a holding device. Jigs and fixtures are used to locate and hold the work that is to be machined. These devices are provided with attachments for guiding, setting, and supporting the tools in such a manner that all the workpieces produced in a given jig or fixture will be exactly alike in every way. The employment of unskilled labor is possible when jigs and fix- tures can be used in production work. The repetitive layout and setup (which are time-consuming activities and require consider- able skill) are eliminated. Also, the use of these devices can result in such a degree of accuracy that workpieces can be assembled with a minimum amount of fitting. A jig or fixture can be designed for a particular job. The form to be used depends on the shape and requirement of the workpiece to be machined. Jigs The two types of jigs that are in general use are (1) clamp jig and (2) box jig. A few fundamental forms of jigs will be shown to illustrate the design and application of jigs. Various names are applied to jigs (such as drilling, reaming, and tapping) according to the operation to be performed.

  • JIGS and FIXTURES Jigs and Fixtures Are Special Purpose Tools Which
    MCE 527- MANUFACTURING TECHNOLOGY JIGS AND FIXTURES LECTURE NOTE JIGS AND FIXTURES Jigs and fixtures are special purpose tools which are used to facilitate production (machining, assembling and inspection operations) when workpieces are to be produced on a mass scale. The mass production of workpieces is based on the concept of interchangeability according to which every part will be produced within an established tolerance. Jigs and fixtures provide a means of manufacturing interchangeable parts since they establish a relation, with predetermined tolerances, between the work and the cutting tool. They eliminate the necessity of a special set up for each individual part. Once a jig or fixture is properly set up, any number of duplicate parts may be readily produced without additional set up. Hence jigs and fixtures are used: i. To reduce the cost of production, as their use eliminates the laying out of wiork and setting up of tools. ii. To increase the production. iii. To assure high accuracy of the parts. iv. To provide for interchangeability. v. To enable heavy and complex-shaped parts to be machined by being held rigidly to a machine. vi. Reduce quality control expenses. vii. Increased versatility of machine tool. viii. Less skilled labour. ix. Saving labour. x. Their use partially automates the machine tool. xi. Their use improves the safety at work, thereby lowering the rate of accidents. A jig may be defined as a device which holds and positions the work, locates or guides the cutting tool relative to the workpiece and usually is not fixed to the machine table.

  • Assembly Setup for Modular Fixture Machining Process
    ADVANCED ENGINEERING 3(2009)1, ISSN 1846-5900 ASSEMBLY SETUP FOR MODULAR FIXTURE MACHINING PROCESS Kršulja, M.; Barišić, B. & Kudlaček, J Abstract: In this paper a model of modular fixture setup relative to cutting forces is proposed, planned and assembled. Positioning is discussed and the best solution is offered. Tool movements influence the final quality of workpiece, and fixture influences tool movements. An example is presented as a possible solution. Modular elements make jigs and fixtures elements interchangeable and reusable, their design then becomes a task of selecting and assembling the proper elements together. Primary criterion used for grouping the manufacturing features to form setups is usually tool approach direction. For load/unload, for pin placements etc. Tool carries the main forces that later form the final shape of the work-piece. Keywords: Fixture planning, modular, Tolerance minimization, jigs, assembly setup 1 INTRODUCTION Precision engineering and careful planning are of utmost importance in the manufacture of work holding solutions. Fixtures are used to uniquely locate, support and secure the workpiece in the correct orientation relative to the machine tool. Companies set up their own standards and conventions to increase designer's work efficiency, in other words, to eliminate the redundant design work by just picking up some standard components. The analysis [1] of the design parameters and specifications utilized in jigs and fixtures design using universal modular jigs and fixtures design system (UMJFS) is an often research topic. The features of fixtures include the type of the fixture (milling, drilling), the shape of the workpiece (rectangular, cylindrical), the size and weight of the workpiece (housing dimensions), and the workpiece material (steel, bronze, plastic etc).

Todd Assistant Professor Graduate Student Department of Mechanical Engineering The University of Alabama Astrionics Laboratory Optics and Radio Frequency Division Optics Branch James W. Bilbro, MSFC Colleague INTRODUCTION NASA uses precision diamond turning technology to fabricate replication mandrels for its X-ray Calibration Facility (XRCF) optics. As shown in Figure 1, the XRCF optics are tubular, and the internal surface contains a parabolic profile over the first section and a hyperbolic profile over the last. The optic is fabricated by depositing layers of gold and nickel on to the replication mandrel and then separating it from the mandrel. Since the mandrel serves as a replication form, it must contain the inverse image of the surface. Figure 1 shows the components of the fabrication mandrel that are necessary to facilitate mounting, handling, and polishing during the fabrication process. V-1 The difficulty in aligning the mandrel Finished Optic comes from the fabrication steps which it undergoes. The mandrel is rough machined and heat treated prior to diamond turning. After diamond turning, silicon rubber separators which are undercut in radius by 3 I! nun (0.12") are inserted between the two end caps of the mandrel to allow the plating to wrap around the ends (to prevent flaking).
