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 Machinist
When people hear the term "paperless," they typically associate the elimination of this office resource as an act that helps the environment. And while this is true, adopting a paperless manufacturing solution can do so much more. In addition to promoting a more sustainable business, going paperless can decrease operating costs, enhance productivity and help a shop floor work smarter (and not necessarily harder).
I was provided with a few opportunities to talk about my STEM project and my career in several schools. It can be a very rewarding experience to a part of. I never saw myself as a speaker or presenter but with my deep knowledge in the subject, I developed a passion for sharing my experiences in manufacturing.
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.
Machining is by far more interesting than what most people know. From the challenges of implementing new complex equipment in the shop, to CNC programming, or even making complex parts in one setup. It is definitely a career choice that most don’t know how advanced it can be, especially the machining of today. Now, we can make parts in one setup that were once made in many setups on multiple pieces of equipment over a long time frame. My career is a success story in manufacturing technology as I have embraced the technology of today.
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.
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.
While recently attending a workshop on starting or growing your school-based enterprise at the school district of Eleva-Strum in Wisconsin I discovered that they have great model for their student-run business. Their program, Cardinal Manufacturing teaches soft skills and employability skills along with learning the technology.
The Red Raider Manufacturing program in the Sheboygan Area School District had 1,090 students in the 2021-22 school year. Its mission is to give all SASD students access to the most up-to-date, relevant and exciting learning experience to succeed. The vision of the program is education and industry partnering to turn a manufacturing/technical career into an aspiration. The students in the program are high achieving, proud of what they do, and career ready.
Here is a great video about Cardinal Manufacturing which is a student-run business in the Eleva-Strum High School. It’s a manufacturing program in the technical education department where the students are responsible for all aspects of the business.
I recently had an opportunity to interview Phil Brown and Umair Riyas from NexGenCAM about how to begin a career in computer-aided manufacturing or CAM. They are applications engineers that specialize in CAM software. Phil and Umair have extensive backgrounds in CNC and CAM/CAD, they offer a few tips to others who may be interested in starting a career in the field.
