Metal Machining: A Subtractive Process

Metal Machining: A Subtractive Process
Working with metal can involve the utilization of a number of crafts and trades. They may work in separate shops or under the same roof. Metal machining is able to work in both capacities. However, many modern machinists find their employment in a fabrication shop. The latter allows them to perform their skills in a work environment where the next step to their workpiece may actually occur in-house. A Controlled Subtractive Process While some manufacturing processes such as welding, are additive, machining is not. It is subtractive. In machining metal, a machinist will remove a little or a substantial amount of metal to produce the desired component. They may have to cut the material down to the correct size or produce a precise shape with exacting internal and/or external diameters. The tools and the techniques reflect this approach. To ensure exactitude, may utilize CNC. The CNC further ensures, the process meets the definition of machining as “controlled” material removal. Basic Machining Processes Metal machining uses specific tools. In general, machinists classify their actions into one of the following groups: 1. Drilling: Drill presses are the most common equipment capable of producing the right size and shape holes in the metal. Alternatively, a machinist can employ a lather or a mill to accomplish this 2. Milling: Milling machines, usually under CNC control, are the major tool for this action 3. Turning: Specific turning tools are lathes However, metal machinists may also bore (thereby improving an existing hole), plane, broach or shape metal workpieces. They may also employ such tools as plasma or laser cutters or EDM for producing specific tolerances in certain metals. Metal Machining Machining is a process, a craft, and a learned skill. Unlike several other metalworking skills, it is subtractive. It does not add but takes away undesired or extraneous metal from a piece. In this way, while not an additive process, metal machining does actually add value to a workpiece. Be the first to like. Like...

Using A Turret Punch Press

Using A Turret Punch Press
While a turret punch press is not a new piece of equipment, new technology has created an effective, efficient punch that can form metal quickly, with precision and accuracy as well as a lower cost than other options. As with all types of punching and pressing. This system uses incredible amounts of force, often in the tens of tons, to tools to punch through sheets of metal. The turret punch press can be used to create simple holes in the metal or, through the use of different tools, it can create a variety of simple to much more complex shapes. Operations Possible With the new options in CNC or computer numerical controlled turret presses, even more, advanced and detailed shapes can be created. Additionally, with the new styles and modes of turret presses on the market, operators can now control the press functioning to increase speed and even create surface etching and patterning on the metal rather than just developing the punched holes of the past. A critical control now possible is the punch cycle. It can be stopped anywhere in the movement to maximize the number of hits per minute the press can manage. The more hits per minute, the faster the production, as well as the more energy efficient the equipment is to operate. Cutting is now also possible with the turret punch press. This is ideal as it allows for a single piece of equipment to be used to create the part, rather than the added cost and time to move parts from one machine to another for further processes. Deburring edges or even tapping can now be done the turret style of punch press. This added versatility has made this an important option to consider for large volume production of a wide range of different parts and components. Full automation of the system is possible with some types of equipment, which makes it an ideal addition to a large-scale metal fabrication shop with a constant requirement for large volume order production runs.

Where Did MIG Welding Come From?

Where Did MIG Welding Come From?
MIG welding is a common process, and many welders in Cleveland prefer it because it’s fast and effective. You don’t have to hold a welding stick, and you can create perfect welds without a lot of practice. In fact, MIG (GMAW) welds are common in many automated welding processes, but where did this method originate? Here is information on gas metal arc welding history and some of the benefits you can receive. Roots in the Bronze Age Early forms of welding were not MIG methods but go back as far as 3000 years ago. Many artifacts show simple but effective welding techniques. However, it wasn’t until 1800 that Humphry Davy discovered that electricity forms arcs. About the same time, Vasily Petrov produced an electrical arc that was continuous, and this makes MIG welding possible in Cleveland today. People used electrodes made from carbon until the dawn of the 20th Century when metal electrodes were commonplace. 20th Century By 1920, General Electric came out with a crude type of GMAW welder. The machine used DC electricity through bare electrodes and the arc voltage regulated the electrode feed rate. It didn’t use any gas to protect the weld. Shielding Gas Using an inert gas in the process shields the weld from many contaminants that weaken the bonding process. Early welds did not rely on shielding gas to keep them clean. Gas welding didn’t happen until the mid 20th Century. Early MIG methods were too expensive for common use because inert gasses weren’t easy to come by. However, by 1953, CO2 made the process cost-effective. By the 1960s, short arc welding methods made it possible to bond sheet metal and thinner materials. Thanks to advances in electric power and electrode technology, MIG welding is very popular in Cleveland and all over the world. Today, the process is an exact science thanks to modern computer technology. Be the first to like. Like...
