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 CNC Machining
A machine tool is a mechanical device that is used to machine metal components. The machine tool is essential in manufacturing processes and is used to cut, drill, and grind parts. A machine tool could be a lathe, mill, or a grinding machine. Machine tools are essential to making precision parts for production machining operations.
Precision machining is the process of removing material from the workpiece and holding a tight tolerance and finish on the part. The process of removing material from the workpiece is usually done with computer numerical controlled (CNC) machines.
The CNC Machining industry has many specialized terms for tooling, machines, and other technology. Here is our list of things to know about machining with CNC equipment.
Blueprint Reading - The term blueprint reading means that someone interprets ideas that are on a drawing or print.
CAD/CAM Software – CAD is the acronym for Computer Aided Design. CAM is the acronym for Computer Aided Manufacturing. They are computer software that are used in the manufacturing industry.
Caliper – A measuring tool that is used to measure internal and/ or external dimensions on machined parts.
CNC is an acronym for Computer Numerical Controlled. CNC is a type of machining practice. Besides CNC the other type of machining is manual machining. In CNC machining the workpiece is held in the machine and the CNC Programmer writes code so that the CNC machine can machine the workpiece. The CNC Machinist sets up and operates the CNC machine and oversees the machining process.
Starting a machine shop can be an overwhelming task. There are many factors to consider while keeping it running efficiently. Besides the operational tasks, we have broken it down on what it might take to have a steady stream of work in your machine shop.
I recently had an opportunity to visit the technical education department at the Eleva-Strum high school. While I was in the shop, there was an eighth-grade class working on manual milling projects, sheet metal projects, welding projects, and brazing projects. These projects that they were making teach the students the fundamental principles of manufacturing. With this class, the students spend six days in each subject area, then they switch to another project. They learn the basics like how to read a tape measure, and how to use a dial caliper.
This book is an insight into how to start a student-run business in your school district. It offers a look inside Cardinal Manufacturing in the Eleva-Strum School District. It defines what a student-run business is and lists the benefits of a program like this. Check it out!
I don’t know a single CNC machine shop that has an easy time hiring machinists, and would say they have enough well-qualified candidates. The fact is that there is more demand than supply, with not enough young people coming into the industry to fill the positions that are needed by machine shops today. On one hand, it's great news in general, that the demand for machinists is strong. Onshoring seems to be a longer-term trend now and the demand for machined parts in North America is strong, which is fantastic. The shadow side is that it’s tough to find machinists and most shops feel that pain, which inhibits their ability to grow at the pace they could theoretically if hiring was not a problem.
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.
A cobot can add a lot of value to the manufacturing process in a machine shop. It can increase the productivity of the CNC machine, while also contributing to process accuracy and consistency. Cobots can be easy to program and are safe to use.
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.
