Introduction to the Ball Bar DumbbellFigure 1., The Ball Bar Dumbbellshown with heavy duty stand and clamp, priced separatelyThe Ball Bar Dumbbell is ultra precise and ultra simple, with the power to evaluate the performance of the entire Coordinate Measuring Machine System in just a matter of minutes. The first step is to understand the Ball Bar Dumbbell concept. This tool consists of two ultra precise spheres of exactly the same diameters that are firmly attached to the opposite ends of a rather long rigid bar. The accuracy of the Ball Bar Dumbbell is only limited by the roundness of the two spheres and their common size. The ANSI B8. 9. 4 1 1. American Tool Quick Grip Micro Bar Clamp' title='American Tool Quick Grip Micro Bar Clamp' />The Performance Evaluation of Coordinate Measuring Machines requires that the quality of the Standard Ball Bar Dumbbell Spheres be round and common size within five millionths of an inch. The spheres for the Ultra Precise Series Ball Bar Dumbbell are held to two and one half microinches. For all practical purposes, these are the highest quality Ball Bars Dumbbells.

McMasterCarr is the complete source for everything in your plant. American Tool Quick Grip Micro Bar Clamp' title='American Tool Quick Grip Micro Bar Clamp' />For proper evaluation, the Ball Bar Dumbbell must be held in a fixed position on the C. M. M. table by an extremely rigid Heavy Duty Stand See Figure 1. The function of the Ball Bar Dumbbell is so unique that it requires an open mind to really appreciate it. The center to center distance between the two spheres is absolutely fixed. A significant characteristic of the Ball Bar Dumbbell is that it has no cosine or alignment errors at all as contrasted with gage blocks. This is because the length of the line that defines the distance between the centers of the two spheres is represented by the distance between two infinitely small center points in space. When this tool is placed in various locations through out the envelope of the measuring machine, the sphere center to center distance should measure exactly the same. Any variation in the measurement of this distance indicates an error somewhere in the C. M. M. system. This concept is referred to as a Volumetric check. Shift 2 Unleashed Reloaded Crack Fix. The truly hard thing to accept is the fact that you are not even required to know the true center to center distance between the two spheres to effectively use the device. A knowledge of the exact sphere center to center gives the Ball Bar Dumbbell additional capabilities especially in evaluation of the scales. Understanding the Implications of Various Deviations in the Ball Bar Dumbbell Length. Strangely, the first step in the Ball Bar Dumbbell process does not involve the Ball Bar Dumbbell at all, but uses the probe characterization sphere instead. Troubleshoot Your Hardware. Before you go cursing your internet provider, give your modem and router a quick reset that is, turn them off and on again and see if. Well suirted for heavy duty assembly, changing tires on big rigs, working on farm equipment, or for use in power plant maintenance, the Ingersoll rand 2940B2 produces. This first step is very important. The triggering characteristics of the probe head and the elastic deflections through out the machine caused by probe contact force must be compensated for See Figure 3. Form errors in the contact tip must also be corrected for before any meaningful information can be derived from Ball Bar Dumbbell checks. Before initiating the computerized probe characterization sequence, take a good look at the data derived from measuring the almost perfect characterization sphere. In most cases, the machine will report substantial deviations in both size and roundness of the master sphere. During the probe characterization sequence, the computer software will automatically compensate for roundness errors of the contact tip, elastic deflections throughout the machine and for lobing in the triggering mechanism of the measuring probe. USA. com provides easy to find states, metro areas, counties, cities, zip codes, and area codes information, including population, races, income, housing, school. Figure 2, Probe Characterization Sphere. The real magic in Ball Bar Dumbbell evaluation comes from criss crossing the Ball Bar Dumbbell. By measuring an angled Ball Bar Dumbbell placed right an angles to any axis of the C. M. M., and then simply rotating its position 1. By moving the same angled Ball Bar Dumbbell to the other side or to the other end of the table and measuring it again, rotational errors around each axis can be determined. Figure 3, Ball Bar Dumbbell with Probe. For more iformation, please see the. CMM Calibration Equipment Directory. How to Choose the Right Ball Bar Dumbbell for your Application. Length. The first choice to be made is how long should the Ball Bar Dumbbell be The length of the Ball Bar Dumbbell is defined at the distance from the center of one ball to the center of the other. As a general rule, the longer the Ball Bar Dumbbell is, the better it will exemplify the geometric errors of the machine. Having said this, a shorter Ball Bar Dumbbell will show up perturbations in the individual geometries better than a long bar. This phenomenon is a very sound reason for measuring multiple length Ball Bars Dumbbells. Our Dual Ball Bar Dumbbell clamp part FS 2. BB is offered as a simple approach to solving this dilemma. This is accomplished by holding two parallel Ball Bars Dumbbells simultaneously. The advantages to this approach are much faster data acquisition and the elimination of temperature distortions, due to multiple handling of the Ball Bars Dumbbells. A good rule of thumb is that the long Ball Bar Dumbbell should be about 8. The second Ball Bar Dumbbell should be one half of the length of the long bar. Ball Size. The next parameters that must be decided are the size, the material, and the quality of the master spheres. A one inch 1. 0. 0 2. Ball Material. The next decision is choosing the ball material. For touch fire or scanning C. M. M. probes that make physical contact with the subject, the standard ball material is a very high chromium, high carbon, Martensitic stainless steel. This ultra fine grained material is through hardened to 5.
