Sheet metal is an incredibly versatile material, and as such there are many different methods that can be used during sheet metal fabrication, especially for cutting the metal. Different cuts are used depending on the reason for cutting, what is being cut, and how thick the metal being cut is.

In sheet metal fabrication, cutting the metal occurs during many steps of fabrication, so it appears throughout the entire process.

1. Shearing

Shearing is probably the most basic type of cutting sheet metal during fabrication. It is frequently used to separate the sheet metal from the larger sheet or roll. It is not meant to create any detail, just to separate a piece of sheet metal into two so that it can be more easily managed and be further processed into the desired shapes.

Shearing uses force and a shearing blade to separate the metal into two pieces.

2. Blanking

Blanking is a method of cutting in which force and blades are used to push out a usable piece of metal from a larger piece of metal. So, the machine would push out the desired shape from a larger piece of metal, and all the surrounding metal would then become scrap. The blank, the piece that was pushed out, can then be further processed into the desired shape needed for the item being built.

3. Punching

Punching is exactly the opposite as blanking, it is a method where a hole is punched into a piece of metal. The piece that is punched out is scrap metal, and the larger piece of metal with a hole or multiple holes in it is the usable part that can then be further processed into whatever is being built.

There are multiple types of punching, each describes a different type of hole that can be made in the metal.

4. Piercing

Piercing is one of the types of punching. It is one of the most basic punching methods used. In piercing, a circular shape of a predetermined size is punched out of the larger metal piece. The punched-out piece becomes scrap. Often, when using piercing in sheet metal fabrication, the exact same machine and method is used as in blanking, except the user just switches out which piece becomes scrap metal.

Piercing is sometimes used as a general word synonymous with punching, however sometimes, as described above, it indicates only the punching out of circular shapes.

5. Slotting

Slotting is another method of punching. Similar to piercing the punching method is used to knock out a shape, however unlike in piercing, the shape that is punched out is a rectangle instead of a circle. This method is sometimes referred to as piercing as well.

6. Lancing and slitting

Lancing is a method which just creates a half cut where the piece is actually still attached to the rest of the piece. This type of cutting sheet metal during fabrication is good for pieces that need vents or louvers. To best describe lancing, it would be cutting three sides of a rectangle, specifically one long side and the two short sides, and then leaving the second long side attached.

Slitting is very similar to lancing, however it is just creating slits in the metal, straight or curved lines cut into the metal that are not a part of any real shape.

Neither of these methods create any scrap metal, as nothing is being punched out of the original piece.

7. Trimming

This method is simply just a matter of removing excess material from any part that has been created. This is a significantly more detailed type of cutting that occurs later in the whole sheet metal fabrication process.

As you get older, you may lose a tooth as a result of decay over time. In the past, many people used false teeth as a solution to this problem. But today, dentists offer the very best in implant technology, meaning you can easily replace a single tooth.

As with any medical procedure, there are often a number of misconceptions about the process. Here, we’ll discuss and debunk 6 common myths about dental implants.

1. People can tell the difference between implants and natural teeth.

Dental implants are placed in the mouth permanently, and are not removable. The materials used to make the implants are as close to natural tooth as possible. Your specialist will also take great care to match the colour of your implants to the colour of your natural teeth.

All of this means that dental implants are indistinguishable from the rest of your teeth to the naked eye. You’ll be able to smile confidently knowing your dental implants blend right in with the rest of your teeth.

2. Dental implants are extremely expensive.

While dental implants are certainly costly, they are very affordable when you consider the value you get out of them. Dental implants should be seen as an investment in the future.

The average dental implant lasts up to 15 years. When you spread out the cost over 15 years, you’ll see that they’re actually very affordable.

Many people can get assistance, or even full coverage from their dental insurance provider. If you’re unsure, you can always ask your clinic to find out what your insurance will pay.

3. Dental implants are hard to take care of.

This myth stems from people’s beliefs about other forms of cosmetic dentistry, such as false teeth. False teeth need to be cleaned and stored properly to avoid damage.

However, because dental implants are permanently attached to your bone, they are cared for just like regular teeth by brushing and flossing.

4. Any dentist can give you implants.

While technically, any dentist could provide you with implants, it’s important to choose a dentist with plenty of implant experience and expertise.

It’s a good idea to shop around for an experienced provider who specializes in implants so you know you’re getting the best care possible.

Read online reviews and schedule a consultation to get a feel for your dental healthcare provider’s qualifications, expertise, and skill.

5. Getting dental implants is painful.

The process of getting dental implants would definitely be painful without pain management. Thankfully, your dental clinic can offer you many pain management options, including local anaesthetic and sedatives such as nitrous oxide gas.

6. Dental implants can have side-effects.

Dental implants are actually made of chemically inert materials including titanium and ceramic. This means they will not interact with the body or cause any side-effects.

This unfortunate myth has deterred many from getting treatment that could improve their smile and their health. But experts agree that dental implants are completely safe and do not cause any unpleasant side-effects.

If you’re in the market for a locksmith, you may have a number of misconceptions about what it is that locksmiths do. Check out this article for the top 5 myths about locksmith services.

1. Anyone can pick a lock.

Lockpicking and locksmithing are two very different specialties. A locksmith does much more than simply pick a lock, including changing the locks, cutting keys, and installing safes and vaults.

Picking commercial grade locks is not easy, and it’s not something that can replace the services of a professional locksmith.

2. Locksmiths are so expensive that I may as well break a window.

Unless you’ve actually looked up the price of replacing a broken window, you might not know that locksmith services are cheaper than replacing the window — not to mention safer and less destructive.

Breaking a window to get back into your house may seem like a good solution, but you can easily get injured in the process.

Before you go to these extreme lengths, call your local locksmith for a quick quote. In many instances, it only takes a few minutes for you to get a price.

3. You can do it yourself.

Locksmithing is simply not one of those DIY projects.

Contrary to popular belief, locksmithing equipment is considered “restricted” to the general public, and for good reason, too. While you may swear you’re only using them to pick your own locks, criminals could use them to gain access to restricted places.

While you may still be able to get your hands on a set of lockpicks, that doesn’t mean you’ll be successful when you try and use them. Lockpicking is extremely difficult and requires hours upon hours of practice to learn. Plus, you’ll probably only get this idea when you’re already locked out!

Leave it up to the pros and hire a professional locksmith.

4. All locksmiths are certified.

You should always verify your locksmith’s credentials before hiring them. After all, you are trusting them with the keys to your house (or car, or safe… you get the picture!).

Some people may be able to acquire locksmithing equipment and learn the basics without qualifications. However, it’s always important to hire a qualified locksmith because they will be bonded and insured.

Be on the lookout for impossibly low prices. This is often a sign that the person you’re hiring is not qualified.

5. A locksmith could keep a copy of my key.

Professional locksmiths deal with keys all day, every day. They’re simply not interested in keeping a copy for themselves. In addition, locksmiths are bonded and insured and would not keep an extra key, as this is a liability.

If you’re concerned that a locksmith Toronto might keep a copy of your key, ask to watch them cut the key. You’ll see that they take the original and trace the new key from a blank, making only two keys total. Any professional locksmith would be happy to let you watch if it eases your fears.

1. You have a leak.

You might notice the paint bubbling on the walls, or perhaps there’s a puddle forming below the sink. Whatever the source of your leak, a professional plumber can help you fix the problem and prevent new problems from arising.

Common causes of leaks include a shift in the foundation of your house, failing parts, and clogged pipes. A professional plumber will be able to identify the source of the leak and put an end to the damage.

Some people don’t call the plumber unless they have a serious problem. But did you know you can use a professional plumber for non-emergency services, like low water pressure?

A plumber can help you determine why your water pressure is low, and help you have those luxurious showers you’ve been dreaming of.

Common causes of low water pressure are clogged pipes, issues with city service, and problems with valves. Your plumber will evaluate the situation, and take steps to restore normal water pressure to your household.

3. Your sink is backing up.

The kitchen sink can clog for a number of reasons, including putting food and grease down the drain. While you may be tempted to try using products like Drano first, these can sometimes fail to resolve the problem.

A professional plumber will be able to clear out the blockage and get your sink back to draining normally. Your plumber will also give you instructions to prevent this happening again, such as installing a fine mesh sink strainer to prevent food particles from clogging the drain.

4. You have no hot water.

As refreshing as a cold shower may be sometimes, it’s not something you want to indulge in every day. A lack of hot water makes everyday activities like bathing, washing dishes, and doing laundry much more difficult.

Fortunately, professional plumbers know how to fix a failing water heater and restore hot water to your house. If you have no hot water, now’s a good time to enlist the services of a professional plumber.

5. You want to install a new fixture or appliance.

Installing a new dishwasher or toilet may seem like something you can do yourself, but making a mistake can cause costly leaks or other damage. It’s a good idea to have a professional plumber install any new fixtures or appliances to prevent incorrect installation.

A plumber can install a new sink, toilet, tub, or shower giving you added confidence in your bathroom and kitchen remodeling projects. Plumbers can also install appliances such as washers and dryers, dishwashers, and garbage disposal units.
