For CNC machinists, operation of the equipment consists of pushing the start button, then paying extremely close attention to what’s going on inside the machine.
It’s pretty common to start off low until you learn how to make things without being babysat. This usually ranges from $12-15 for the first bit, and then you’ll steadily go up from there. Of course, this all depends on where you live and who you’re working for.
Measurements aren’t limited to simple dimensions. Machinists also often need to check things like material hardness and surface finish.
Either way, let’s go over the general process of machining. This will give you a good idea of what machining is really like.
According to most sources, the average US wage for a manual machinist is about $20/hour. Keep in mind that this is the average, so half is higher, half is lower.
First off, the machinist needs to analyze the requirements. This might come in the form of an engineering drawing, a 3D computer model, a napkin sketch, or Farmer Joe trying to explain it from behind all his missing teeth.
When choosing a board grade you need to consider whether the final application is image based, performance based or both. If the requirements are for image based materials then it is best to look at the finer flute profiles (R, E, F and N flutes) as these provide the best surface finishes due to the greater number of flutes per metre supporting the top liner. However, when both image and performance are required then you need to consider utilising a double wall grades (RB, EB, EE, NE) as these also incorporate the finer flutes but with added strength/performance.
Computer control also allows for much more complicated machines. Some have multiple cutters, others are able to simultaneously tilt and move in order to cut all sorts of fancy shapes.
Besides that, we’re often making components that need to precisely fit to other components that we don’t have access to. That means that we can’t just fit it up and see how good it is. It has to be right, and we prove it by measuring it accurately.
Sometimes this is super straightforward; toss a rectangular piece of stock in a vise and call it a day. Other times, this is extremely complicated. For example, think about a casting that doesn’t have a single flat surface.
I've been working in manufacturing and repair for the past 14 years. My specialty is machining. I've managed a machine shop with multiaxis CNC machines for aerospace and medical prototyping and contract manufacturing. I also have done a lot of welding/fabrication, along with special processes. Now I run a consulting company to help others solve manufacturing problems.
I really like using rebar for making all kinds of industrial-looking welding projects. It's also useful for things like reinforcing concrete, surprisingly. There are also a lot of different tools...
Machinists might also need to be very familiar with processes like heat treating. This can be a very common process in some shops, and can take a reasonable amount of skill to get right.
Measurement is a major part of machining. We work to really tight tolerances, and the only way we know that something’s good is by proving it. Machinists often work to tolerances of 0.001″ and sometimes even down to 0.0002″.
Millwrights are focused on industrial equipment repair. They’re generally not as specialized with machining, however they make use of a lot of other skills. Some examples are electrical wiring and welding.
For example, in many repair shops, a machinist might need to be familiar and comfortable with welding. He might use a welding machine to add material to a worn-out part to that he can cut it back down into the required form.

Really, though, if you’re just in it for the money, become an electrician or a plumber. In this twisted world, it’s easier to learn and it pays better.
In reality, the work and skill that’s expected from a machinist is varied and demanding. It’s definitely not a boring job!
This is because parts are created in such insane quantities. Since everyone is bidding on this high volume work, there’s a lot of competition to be the best. Here are some possible types of parts:
This means understanding different shapes, cutting angles, coatings, edge preparations and substrates. There are a lot of very specialized tools that are manufactured to produce industry standards. The machinist will choose a tool that’s not only capable of creating the required features, but also that can produce them efficiently.
There are actually a lot of skills that need to be mastered (more or less) by a machinist. It’s often a very mentally engaging position.
The CNC machining industry, however, is huge and growing. North America is known for producing some really high-quality, complex parts. There are always new innovations rolling out that will keep machinists in high demand for decades to come.
Are you looking for a career and are wondering what it would be like to become a machinist? Or maybe you know someone that says he’s a machinist and have no clue what that means.

Barriers provide the opportunity through constructional design and product flexibilityto create cost saving solutions without affecting performance.
Other machinists might need to be familiar with assembly and disassembly of mechanical systems, like automotive, heavy equipment, or hydraulics.
If those numbers mean nothing to you, an average piece of printer paper is about 0.002″ thick. Now slice that paper thickness 10x over and you’ll have that 0.0002″ precision that can be expected.
For example, tool and die makers are people that specialize in making things like cutting and forming dies for sheet metal work, as well as moldmaking for things like plastic injecting molding or metal casting.
Manual machines are basically machines that aren’t controlled by a computer. They can have power feeds for semi-automatic movement, or they could have a bunch of cranks and whatnot to move the machine around.
Corrugated board strength
These are a few of the things that a machinist needs to review before starting the job. For some parts, you can glance and cut. Some parts take days to plan out.
For CNC machining, you can expect to make a bit more. $25/hour is a reasonable expectation once you’ve got some years under your belt. If you get into the complicated stuff, like multiaxis milling and lathe lovechilds, you’ll do even better.
It’s true that computer controlled machines are gradually replacing manual machines, but there will always be a place and purpose for manual equipment. For example, they’re great for making small batches of parts and for making repairs.
At the end of the day, most guys do this because they enjoy it. There are usually lots of opportunities for overtime, which can make you a reasonable amount of money quickly.
The machinist will also need to pick out appropriate cutting tools. For some jobs, this might mean ordering something that isn’t in stock. There are thousands of tools to choose from, and the machinist needs to be very familiar with how to pick one that fits the requirements.
I've been involved in metalworking in its various forms for the past 14 years. On this website, I share some of the really cool things that I've learned while working in all kinds of different shops.
Of course, this will all depend on the company that a machinist works at. Some companies produce very basic or repetitive types of parts, so the work might become pretty dull after a while.
Forge welding is essentially the oldest way of joining two pieces of metal together. Some say that it's been around for almost 4,000 years, starting from when people were learning to smelt iron from...
There are loads of different devices out there that are designed for different kinds of workholding. The machinist needs to either match up the part and operation with appropriate clamping, or design and produce something that will be effective.

CNC machines are often similar to manual machines, except that they’re controlled by computers. This allows them to make parts that are much more complicated, and they can do it significantly faster once set up and programmed.
If you’re looking to make a lot of money, there are easier ways. That said, the pay’s really not all that bad. A lot of it will depend on career choices you make.
The CNC machinist will need to specify exactly where workholding like clamps and vises will be located, the stock size of the material to be cut, and orientation(s) of the part to accommodate machine ability.
Machining can be as advanced or as basic as you want it to be. This is cool because you can always find a job that fits your ability and skill set.
Here’s a basic outline that explains the machining process. I’ll explain what the step is and what skills are needed to pull it off successfully.
This is another demanding industry. Obviously the quality control needs to be very high, especially for parts that will end up in the human body.
If the part is to be cut on a computer controlled machine (CNC), it will need to be programmed. Simple operations might take two minutes, complex components might need 2 weeks or more.
In current practise Single wall corrugated for outer containers will typically incorporate either R, B or C flute with E flute being mainly used for inner containers, fitments or display work.
Generally this is referring to making airplane parts, although occasionally you might get the opportunity to make something that goes up into space. This is an industry that prefers to use CNC machines to produce small batches of tricky parts. Here are some of the things you can make:
Flute direction is particularly important when using AbbeyLiteTM as it is important to feed the litho press with the flute running at right angles to the litho grip edge (see diagram), this allows the sheet to curve around the printing cylinders without breaking the back of the board.

Both types of machining take a lot of skill. The machinist needs to make some very precise calculations and be able to listen to the sounds of the machines as they work. They need to pay attention to tools as they wear out so that they can be changed before they snap and damage something.
Whether the operations are done by manual or computer controlled machines, the machinist will need to load up the part in the machine, clamp it securely, and accurately orient or measure the orientation of the part.
Many of todays modern Offset presses are capable of printing on AbbeyLiteTM. For those printers considering it for the first time the following information may be useful.
The real answer is that it depends on where you work. Some shops are complete dungeons, others are pristine. The work itself, though, is really cool.
The challenge with mass-produced automotive parts is getting costs down. You’ll rarely see operations that are as efficient as automotive processes.
Pretty much any kind of mechanical component that you can think of. There are a few examples based on the different industries you might get involved with.
What does a machinist do? A machinist works with precision cutting machines to produce extremely accurate mechanical components. These machines may be manual or computer controlled. Parts may be produced in a variety of materials, commonly metal or (less commonly) plastic.
Machinists use a whole slew of measuring tools, all of which require skill and familiarity to use correctly. Here are some examples of what you might run into:
The Sheetfeeding business of DS Smith is one of the leading suppliers of speciality corrugated board. They have remained at the forefront of corrugated material development for many years and pride themselves on quality and technical expertise. Their product range continues to expand as the applications of corrugated board moves into wider markets. Sheetfeeding is one business serving different market needs and no other organisation has invested more in specialist corrugated sheet manufacturing than DS Smith.
The machinist will often slow the machine down, pause it to double-check, and fine-tune the cutting parameters to get the best results. This can be a little stressful on complicated operations. CNC machines are very high powered and easy to crash.
For manual machinists, this involves manually setting the machines and cranking the handles and dials around to cut the parts. Machines with power feed are becoming more common, which means that the manual work isn’t quite so… manual.
This is a really steady industry, and there’s a lot of work to be done. Agricultural equipment takes a lot of abuse, and the parts need to be made to stand up.
