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
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; )
While spending much of my career working in the medical machining industry, it was an education into complex part machining. What is being done today in the machining industry is exceptional. Now a highly engineered part can be made compete in one setup in a machine that can turn, mill, drill, hob, broach, thread whirl, and gun drill parts. I have implemented lathes from 5-axis models up to 11-axis models. Here is a breakdown of what it might take to implement advanced lathes.
When I got started in machining, I really didn’t know what kind of tools to purchase. There is a vast variety of tooling to use in the shop, from inspection tools to hand tools. While having a limited budget, I had to choose to first buy the tools that I thought that I would use the most. This will vary from machine shop to machine shop often dependent on the type of work that the machinist does. Here is a list of some of the more popular choices for tools:
Machining and Tool & Die Making is what I have spent most of my career doing. There is something to be said for being able to turn a raw piece of material into a complex finished part. Through all my roles in the machine shop environment, I have identified a few soft skills, hard skills, and technical skills to have mastered if you want to be a great machinist.
Gage blocks (also known as gauge blocks) are inspection tools that are used in the machining industry. They typically come in an 81-piece set and the sizes in the set are as follows:
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.
In the realm of manufacturing, the production process often relies on various aids such as jigs, fixtures, and specialized tools to ensure efficiency, accuracy, and quality. Traditionally, manufacturers would outsource the production of these components, which could be costly, time-consuming, and limit flexibility. However, with the emergence of 3D printing technology, manufacturers now have the ability to reduce their reliance on outsourced manufacturing aid components.
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.
Amy Vasey is an Automation Design Engineer at HellermannTyton. She has been with the company for 20 years and recently helped introduce and implement 3D printing in their Automation department.
The product development group at HellermannTyton, familiar with additive manufacturing technology, approached Amy’s team, asking if they’d ever considered 3D printing some of their many aluminum parts.
At the time, Vasey and her team weren’t familiar with the technology or where to start. “The product development team was really good at pushing us to start with something small, and that’s what we did.”
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.
Cardinal Manufacturing is a student-run business in the Eleva-Strum High School. In a student-run business the students are responsible for all aspects of the business. It is a custom job shop that makes machined parts for community members and people throughout the country. Check out this video on the program.
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.
Cardinal Manufacturing in Strum Wisconsin is a school-based manufacturing program that operates both as a class and a business as well. The students gain real world life experiences while enrolled in the program. These experiences include problem solving and working in professional roles.
