(HPACs), which have a discharge pressure above 1,000 psi They can also be classified according to the design and principle of operation: 1. Rotary Screw compressors 2. Turbo or Axial Compressors. 23. There are other design types of compressors also, but the general type is given above. These are also differentiated on the surfaces used for locating, but the most common is the 3-2-1 locating principle presented in Figure 4. Here locator L1 constrains the z DOF, locator L2 acting in

Between these two functions, the 6 (3 translation and 3 rotation) degrees of freedom are constrained, while effectively positioning and orienting the part during processing. The location of box-type parts is usually achieved using the 3-2-1 principle. This principle locates the primary plane Design of Milling Fixture in Mass Production of Pivot Block

3-2-1 Principle of Location used in Jig & Fixtures: [1] It is also known as six pin or six point location principle. In this, the three adjacent locating surfaces of the  Fixture Design/Planning In Practice (1). • Many dedicated fixtures for prismatic parts are designed using the “3-2-1” locating principle. proposed a model of modular fixture setup to improve designing of fixtures for different workpiece based on their machining needs (Krsulja, Barisic, and Kudlacek  surfaces used for locating, but the most common is the 3-2-1 locating principle presented in Figure 4.
