Have you heard of ultrasonic machining? Also known as ultrasonic vibration machining, it’s a manufacturing process that’s used to remove material from a workpiece through the use of high-frequency vibrations combined with particles. An ultrasonic tool essentially creates many small vibration

Manufacturing companies use a variety of processes to remove unwanted material from workpieces. Some of these processes are relatively simple, such as cutting and drilling. Others, however, are more complex. Abrasive jet machining falls under the latter category. It involves blasting a workp

What is Chemical Machining? Chemical Machining is the clean removal of metal from pre-described areas without altering the integrity or properties of the metal by means of a photochemical process. This process is primarily used in creating small thin metal parts of the complex design with no

What is Electrochemical Grinding(ECG)? Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in

What is Ion Beam Machining? Ion beam machining (IBM) is an important non-conventional manufacturing technology used in micro-/nanofabrication, using a stream of accelerated ions by electrical means in a vacuum chamber to remove, add, or modify the atoms on the surface of the object. In IB

What is Plasma? Plasma is one of the four fundamental states of matter, first systematically studied by Irving Langmuir in the 1920s. It consists of a gas of ions atoms or molecules that have one or more orbital electrons stripped (or, rarely, an extra electron attached), and free electrons.

What is Surface Finish? Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true

What is Surface Roughness? Surface roughness, often shortened to roughness, is a component of surface texture. It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are s

Frames of bicycles or motorcycles, trailers for trucks, profiles of rail vehicles, materials in space travel – aluminum is the material when it comes to reducing weight and still achieving stability. In addition, a beautifully welded aluminum seam is a real eye-catcher. Thanks to its low den

What is CNC Machining? CNC stands for Computerized Numerical Control. CNC machining is a computerized manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from

What is Shaper Machine? A shaper is a type of machine tool that uses the linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical. A wood s

What is a Grinding Machine? A grinding machine, often shortened to grinder, is one of the power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel’s surface cuts a small chip from the workpiece

What is Underwater Welding? Underwater welding is performed while the welder is submerged, often at elevated barometric pressures. This introduces a variety of challenges that require specialized skills and training that are taught at CDA Technical Institute (formerly Commercial Diving Acade

What is a Drilling Machine? A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver chuck. with hand-operated types dramatically decreasing in popularity and cordless battery-powered ones proliferating. A drilling machine, also

What is a Boring Machine? A carpenter’s boring machine is a hand-driven machine to bore holes in beams such as in the process of making a mortise or making holes for the wooden pegs which hold mortise and tenon joints together. Boring machine, device for producing smooth and accurate hole

What Is a Micrometer? A micrometer is a measuring instrument that can make extraordinarily precise measurements. Most micrometers are designed to measure within one one-thousandth of an inch! That’s a close fit. Exact measurements like this are necessary when even the smallest of space betwe

What is A Planer Machine? A planer is a type of metalworking machine tool that uses the linear relative motion between the workpiece and a single-point cutting tool to cut the workpiece. A planer is similar to a shaper but larger, and with workpiece moving, whereas in a shaper the cutting to

What is a Broaching? Broaching is a machining process where a sharp, hardened, toothed tool removes material from a workpiece in a consistent, continuous, and accurate way. The process of broaching uses a tool with raised teeth of differing sizes that precisely cut away a specified amount of

What is Casting? Casting is a manufacturing process in which a liquid material is usually poured into a mold that contains a cavity of the desired shape and then allowed to solidify. The solidified part is also known as the casting, which is ejected or broken from the mold to complete the pr

What is Spot Welding? Spot welding (also known as resistance spot welding) is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area. It works by contacting
