Planning/Concepts Planning Steps 1-10
Step 1: First, determine the nature of the operation to be performed, the number of parts to be processed per cycle, and whether operations will be performed on more than one surface of each part. Also, determine the time that should be allowed for part loading, unloading, and clamping. In the initial phases of system planning, include adequate measures and devices to ensure the safety of workers and equipment. For more information, see the safety section on the back inside cover. Step 2: Prepare an outline of the sequence of events that will take place during the manufacturing cycle. This will assist you in determining the types of circuits that you might need, as well as any external control (such as a tie-in with machine controls) that your application may require. Step 3: If you are fixturing for a machine operation, calculate the cutting forces generated in the machining process and note the direction that these forces tend to act on the workpiece. If you are planning a retrofit of a manual clamping system, you may use the torques presently being used. However, it is recommended that cutter forces be calculated as a precaution in such a case to ensure that clamping devices are sized to provide an adequate margin of safety. The operation manuals of many machine tools contain tables that list machining forces or simple formulas for calculating these forces. However, if you can’t find the information, give us a call. We’ll be glad to get you started.
Step 10: Call us for help. Our application engineers do not design fixtures. Their job is to help you use pneumatic clamps successfully, whether you are retrofitting existing fixtures, need an idea (concept) for clamping a new part or want a quick review of your design, we stand ready to help you. Call: 800-992-0236 for everything you need in power clamping... Discover how easy, economical, and efficient power clamping can be with one toll free call. We’ll be glad to answer your questions, provide concepts or advice, and give you a quote.
Step 4:
A-1
When planning for a machine operation fixture(s), plan with positive fixed stops to resist the majority of the cutting forces and to ensure correct location of the workpiece, using the primary part locating features. Step 5: After you have determined the machine cutting forces, it’s easy to calculate the clamping forces required to hold the workpiece on the fixture or machine table. Again, a simple formula is all you need to arrive at an answer for the materials you’ll be using. Give us a call if you need help. Step 6: Determine where clamps should contact the part to hold or support it securely and to avoid interference with operations. If clamps cannot be located so as to avoid interference with manufacturing operations, it will be necessary to use an external control device to move the clamps out of the way as the need arises during the manufacturing sequence. This will require that electrically actuated valving be used to control the offending devices separately. Step 7: Determine the type and number of clamping devices you need based on the total clamping force required and clamping positions you’ve selected; on the size, strength and shape of the part; and on the operation. Step 8: Select valves and other control components to accomplish the sequence of operations you outlined in Step 2 . See the valve section of this catalog for guidance. Step 9: Finally, select the plumbing components required to connect the air supply to the valves and devices. Simply review your system specifications and layout to determine what you need in terms of ratings, sizes, and lengths.
