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.”
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.
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 manufactures parts for community members and people throughout the country.
They are having an open house event on May 8th, 2024, from 4pm to 9pm. Come checkout what makes this program so great!
My first project in technical collage for tool and die making was to make 1-2-3 blocks. I milled the blocks oversize to leave stock for precision grinding. After drilling and tapping the holes in the blocks, we case hardened them. The last process was to precision grind them to size. The grinding process involved both grinding to blocks to size and to a squareness tolerance.
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.
Over the past 10 years, productivity in the manufacturing industry has increased 1.2% compared to 2.6% in the previous 7 years. Emerging technology trends are disrupting the manufacturing industry, creating a need for increased innovation to remain competitive.
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.
Over the years, SOLIDWORKS has evolved with the help of customer feedback, making it easier and faster to use. Each SOLIDWORKS release aims to fulfill customer requests and improve automation, making it easier to work smarter, faster, and together. SOLIDWORKS 2023 3D CAD is no exception.
This mechanical clock in the video was made with over two dozen 3d printed parts. It has brass bushings and steel shafts. It was inspired by a mechanical watch design, but the parts are laid out in-line and scaled up six times larger than a mechanical watch.
