The workflow varies from shop to shop, but we will breakdown what it might take to process a CNC lathe part.
Machining.Blog® is a weekly blog focused on manufacturing career development. It features blog articles on the fundamentals of manufacturing for aspiring machinists. Our goal is to create an interest in manufacturing in the USA. Our writer Matthew Schowalter has worked in manufacturing for 24 years, and he covers the topics that matter to someone starting their career in manufacturing.
“The soft skills the machinist uses are the unseen tools in their box and can directly impact the success or failure of a dreamed after machining career.”
All in Manufacturing
The workflow varies from shop to shop, but we will breakdown what it might take to process a CNC lathe part.
The machining industry has thousands of CNC machine shops. Many of them struggle to stay profitable and deliver on their promises, and as a result, don’t grow as fast as they want to. A small number of shops are highly effective and grow faster than the rest and go on to have amazing results. I’ve talked with thousands of machine shops around the world and seen the common themes, and of course, with our own experience growing a shop from $0 to $12M in revenue, we have a few thoughts to share today. There are many more effective habits that are also important, but here are the most important habits we’ve seen over the years.
Adapting to the worker shortage in manufacturing is difficult. Some shops may choose to search more aggressively for employees, while others might invest in technology that helps streamline the manufacturing processes. Then there are other manufacturing facilities that may buy another machine shop to gain capabilities. Those are all ways to overcome the worker shortage, but this article will focus on how to introduce manufacturing to the younger generation to help fix the worker shortage.
The machinist’s role is to setup advanced CNC machines and monitor the cutting conditions as the machine makes parts. As the machinist makes the parts, they inspect the parts with inspection tools and adjust the CNC parameters to achieve a conforming part that is within specifications.
There are many terms to know and understand in the machining industry. If you are just getting started in the industry, we have designed this list to better prepare you for the job.
Over the last 5 years, I have been observing the manufacturing industry worker shortage. The drastic change that I have seen over my 24-year career is alarming. While most industries change over time, I believe the changes that are happening to manufacturing are more than that. We are in a worker shortage crisis.
There are fifteen parameters to be considered when analyzing a new part to be made in a CNC lathe. While this may seem like a lot of considerations, if you examine a part properly you will be successful in its implementation. Here are the parameters to consider and the questions to ask:
Knowing what features to inspect on machined parts, being aware of machining conditions, and what items and details to deburr can make all the difference in the success of the manufacturing project. By mastering these three items, it will set you apart as a great machinist. Let’s review in detail.
Each program has a program number, that should be different from other program numbers
Each line of code in a CNC program is called a “Block”. It contains G and M codes in it.
The block cannot have two M-codes in it
The ending of a Block has a End-of-Block symbol and it is a semi-colon. (Example: G1X.5; )
How we are taught how to pronounce a measurement in mathematics class is different from how we pronounce a measurement in machine shop class. In the following chart, I will break down the decimal place pronunciation of 0.123456.
An endmill is a cutting tool that is typically used in a milling machine, or a mill/turn machine. They come in various diameters and lengths, to suit the needs of the user and the application. With that, they typically come in variations with 2-flutes, 3-flutes and 4 flutes. A 2-flute and 3-flute endmill is typically used in cutting aluminum. The 4-flute version is used in milling steel. The versions with 5 to 12 flutes are used in finish cutting steel.
If you work in the Manufacturing Industry chances are you have seen firsthand how the skilled manufacturing worker shortage affects your job. When there are more people retiring and less new people coming into the field, it can have negative effects on the industry. I have looked into the worker shortage crisis since 2015, and I came up with a phrase to help fix the shortage, “We Must Communicate, Collaborate, Connect, on a Consistent Basis”. I call it the 4-Cs of manufacturing.
Your company tries SO hard to make everything perfect, but occasionally, something slips through the cracks, and you send some parts to a customer that get rejected. It’s not a fun situation, and it can be like a gut punch, depending on how expensive the mistake is. How you handle it from the customer’s perspective can make all the difference and even potentially turn a bad situation into a positive experience. Customers know that mistakes will happen, but how a vendor responds to them can put your relationship on the chopping block, or solidify your position in the partner category.

Tribal knowledge can be a killer. For a smaller, stable company not on a growth path, it probably isn’t the worst thing ever – unless you lose one of your long-term employees who is the only one that knows how to do a lot of things. Certainly for any company that is on a more dynamic path for growth, adding new customers, more employees, or is concerned about losing that knowledge of a key employee it can be a major problem. Having your companies’ processes and procedures be locked in the brains (and only the brains) of your employees can be very difficult when you lose someone.
