### Uncertainities in Topology Optimization

Various types of uncertainties are considered in the topology optimization, like uncertainty in loading, geometry and material properties, etc. Two methods account for the uncertainties in the topology optimization framework. They are- 1. Probabilistic based methods (Statistical or reliability-based methods) 2. Non-probabilistic based methods The traditional approach to account for the uncertainties in the structure […]

### Generating G-code using Fusion-360

I recently tried to use the Carvey machine to carve a geometry for the project on the Caustic phenomenon. But, the problem started when I realized that only vector format files or G-code could be imported to carry on the operation in that machine. Since the 3D geometry file can’t be converted into a vector […]

### Nonlinearities in Structure

When the force-displacement relation of the system is linear, then that particular type of system is named as “linear system.” The simplest example of such a system is mass-spring mechanical assembly. In this mechanical system, the stiffness of a spring remains constant. But in real-world problems, the stiffness of a system is not linear; however, it may be idealized […]

### Carving on Acrylic sheet using CNC-machine

Carving is a subtractive manufacturing/machining process in which the tool scrapes out the material from the workpiece to generate the desired shape object. The process has been here for centuries; sculptures made of stone or paintings inside the caves are examples. Advancement in Computer-Aided Manufacturing (CAM) has modernized the traditional carving process. Nowadays, Computerized Numerical […]

### 3D printing

3D printing as the name suggest is a method of creating a three dimensional object layer by layer from a CAD model. 3D printing is an additive process where materials are added to build the desired geometry, as opposite to machining (subtractive manufacturing) process in which material is cut off or removed from larger block […]
