The stretch feature of CNC milling is a modeling method that extends a section along the direction perpendicular to the section to form a solid. The stretch feature is also the most commonly used feature modeling method. Select the stretch button in the basic feature toolbar. The shape shown in Figure 6.9 and figure 6.10 is a model designed by using the stretch command.
Rotation of CNC Milling:
Rotating feature is a modeling method to generate a solid by rotating a sketch section around a centerline. The rotation button in the toolbar is. Rotating features are used to generate rotating parts, such as rotating shafts, gears, etc. The step shaft shown in Figure 6.11 is a model designed by using rotating life.
Scanning of CNC Milling:
Scanning feature is a modeling method to generate solid by extending sketch section along trajectory curve. By selecting the scanning command, the scanning features can be divided into constant profile scanning and variable profile scanning. The scanning feature modeling method in the form of constant section is a relatively simple scanning method, whose sketch is cut while the shape remains unchanged. The scanning method and generation method of the sketch section are controlled by the scanning trace line of the variable section scanning feature Set the geometric relationship between the sketch object and the scanning track in the sketch section drawing project In this way, the sketch section is scanned along the origin track. Maintain the geometric relationship with other tracks, so as to generate a solid model with variable shape.
