TOOLS AND EQUIPMENT

The CSUDH Fab Lab has a variety of innovative equipment that is currently expanding. We hope to provide the most modern equipment for students to learn and expand their knowledge. While utilizing the equipment students learn about its operation. Below you can find the most current equipment in our Fab Lab.

The laser cutting is the practice of engraving and cutting an object. The technique does not require the use of ink, nor physical contact with the surface. By using a high frequency light of charge carbon dioxide, the object is cut and engraved. The laser cutter can cut and engrave material such as cardboard, plastic, acrylic, and wood. By adjusting the speed, power and frequency of the laser optimal engraving and cutting can be achieved on any material.

The precision milling is a machining process of using rotary cutters to remove material from a workpiece by advancing (or feeding) in a direction at an angle with the axis of the tool for a precise shape or size. Unlike standard drilling machines that are limited to a single axis of motion, precision milling machines move along multiple axes (X, Y and Z). This allows milling machines to contour 2D and 3D shapes efficiently and precisely in a wide variety of metals such as 300 and 400 series stainless steels, aluminum, brass, titanium, L605 and other specialty alloys. When a part is milled, it is held in place on a moving table (or bed) with tools such as vices, V blocks (to hold cylindrical seamless tubing) or step clamps. A rotating cutting tool, housed in the machine head, is brought down onto the part while chips are removed via a cooling lubricant. The cutting head of a milling machine typically has saw shaped teeth. Straight teeth are more effective when cutting dense materials, while helical teeth are more effective when working with softer materials. It is important to note that because the milling process applies significant pressure to machined parts, weak or thin shapes are more difficult to mill, as are shapes with irregular edges. CNC milling machines are usually grouped together by the number of axes on which they operate. Most machines operate within three to five axes. In general, the X and Y axis of a milling machine moves the part back and forth within the horizontal axis while the cutting tool moves vertically within the Z axis.

Using filament composed of different material but most commonly used is ABS a sturdy oil based resources. The 3d printer can print out 3d object design on CAD. The 3d printer follows a set of commands called G-code the object is sliced into many layers in which the 3d printer follows the g codes commands along the x, y and z axis. The infill of a 3d print can also be changed to make either the object more solid or hollow inside of it. The 3d printer can print out objects cars, tools, and in the future food.

The computer numerical control or known as the CNC can preform the functions of drilling. CNC machines follow axes labeled X and Y for horizontal movement, and Z for vertical movement. Using a set of commands called the G-code it follows those commands to drill or engrave the design into the wood or material being used. The CNC machine is capable of also scanning 3D object into a 3D computer model using specialized drill bit allowing the user to analyze and modify the object on their computer.

The circuit production is the process of removing areas of copper from a sheet of printed circuit board material to recreate the pads, signal traces and structures according to patterns from a digital circuit board plan known as a layout file.

The Vinyl cutter is used by professionals to make signs and billboards made from vinyl that is adhesive allowing it to be applied on any clean surface. The vinyl cutter uses a small knife to follow a set of commands that lead it through the x and y axis. The pressure of the small knife allows for deep and clean cuts through vinyl or any other material such as paper, cardboard, or thin plastic. The vinyl cutter has the capability to cut any complex design allowing expansive creativity.

Electronics will include coding, programming, circuit board, and assembling products. Electronics is distinct from electrical and electro-mechanical science and technology, which deal with the generation, distribution, switching, storage, and conversion of electrical energy to and from other energy forms using wires, motors, generators, batteries, switches, relays, transformers, resistors, and other passive components. This distinction started around 1906 with the invention by Lee De Forest of the triode, which made electrical amplification of weak radio signals and audio signals possible with a non-mechanical device. Until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers, and vacuum tubes. Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of solid-state physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. This article focuses on engineering aspects of electronics.

The vacuum forming allows for precise 1 to 1 scale molds of object placed in Formech vaccum former. The molds can be made from material such as plastic, foam, HIPS, and PVC. The Formech can be used to make car body shells, display trays, masks, and packaging. By using the vacuum mold alongside 3D printing the prototyping of designs can be accomplish quickly and efficiently.
