Micro turbine

  1. 1. Introduction PRO E or Pro Engineer is software used for designing purpose. It is the product of the company Parametric Technology Corporation. Pro Engineer Wildfire is a computer graphics system for modelling various mechanical designs and for performing related design and manufacturing operations. The system uses a 3D solid modelling system as the core, and applies the feature- based, parametric modelling method. In short, Pro/Engineer is a feature-based, parametric solid modelling system with many extended design and manufacturing applications. It was the first CAD system entirely based upon feature-based design and parametric modelling. Today most software producers have recognized the advantage of this approach and shifted their product onto this platform.
  2. 2.  The basic functionalities of pro engineer are divided into different modes: Sketch - Used to sketch the geometry for the model to be designed. Part Used to create features of a model. Assembly Used to create an assembly design by assembling various parts or features of the model. Drawing -Used to generate the drawing of the parts and assemblies created in the part and assembly mode. Manufacturing To make the designing process simple and quick Pro E is divided into above mentioned modes, which is required to complete the designs.
  3. 3.  Extrude command The extrude option is present in the part mode of pro e. It is used to sweep a sketched section along a straight trajectory. While using the extrude command the section is to be drawn in the sketch mode and then the depth of extrusion is defined as per dimensions, after defining the depth the section is protruded up to the value of depth defined.  Circular Circular command is used to make curved surface on the vertices of a two dimensional entity. It is used to make the corners of the entity in a circular shape. Explanations of command
  4. 4. This command has features same as fillet command.  Pattern Pattern command is used in the sketch mode of pro e. it is present in edit option in the menu bar. Pattern is a versatile tool which makes designing process very easy and efficient. Pattern command is used to create multiple copies of the feature with less effort.  Trim There are three trim command options. Delete segment, corner, and divide. The option can be accessed through either the edit pull-down menu or the trim icon on the sketcher toolbar
  5. 5. Delate segment automatically divides sketched entities at any point of intersection, thus allowing you to simply delete the unwanted geometry. Corner requires the selection of two entities. It finds the intersection of two selected entities and either extends or trim the entities up to the intersection. Divide will divide any sketch entities at the point of selection for as many selection as desired
