Development and analysis of parametric pictures of mold standard parts
The production of animation essentially relies on the continuous playback of still images. This process requires a large number of individual frames, making it extremely challenging to manually define the position and shape of each one. By using 3DStudioMAX for 3D animation, this task becomes significantly easier. The software allows users to define key positions of objects along the timeline, and then automatically calculates the intermediate frames, resulting in smooth and natural motion.
In terms of modeling typical mold structures, most components are standard parts, with only a few requiring minor modifications. To streamline the process, you can import AutoCAD DWG format 3D files or merge parts from existing MAX files. Using the "File/Merge" option in the menu, you can select and insert the required components. These parts are then assembled according to their actual positions within the mold, ultimately creating a detailed mold drawing that follows a standard structure.
For example, when designing an overall animation for a V-bend operation, the process involves the bending punch moving downward at a constant speed. Once it makes contact with the pressing member, it stops and then lifts back up to complete the bending cycle. This sequence is crucial for simulating real-world mechanical behavior.
To begin, turn on the Autokey function while the upper template is in its original position. Move the frame slider to frame 30 and reposition all parts connected to the upper template so they align with the clamp and punch. This creates the base of the animation. When played, the upper mold will move down as expected. To adjust the movement, use the TrackView-CurveEditor to modify the curve parameters, allowing for smoother and more controlled motion.
By carefully planning keyframes and refining motion curves, animators can achieve highly realistic and efficient 3D animations, especially in complex scenarios like mold assembly and mechanical operations.
