A computer numerical controlled (CNC) machine controls tools, such as a lathe or mill, using a computer program to achieve incredible precision. Just about all industries rely on these custom machined parts and have been for decades. Yet, there are still some myths that give people the wrong impression about CNC machining.
Culture is the soul of a company.
It’s what motivates people to do great work each day (no, it’s not money or health benefits or time off … although those are ALL very important). It’s true: Over 50% of workers said that company culture is more important than salary when it comes to job satisfaction.
Company culture is obviously a vital part of a successful organization, but it’s a tough thing to define and even tougher to create. But, it’s not impossible, so we’re going to tell you how to build a company culture that elevates company pride, boosts morale, lowers turnover, and inspires productivity.
The metalworking industry needs more CNC operators. This rewarding career appeals to people who have a broad skill set: a good eye for detail, math, mechanical design, and the ability to read technical drawings. CNC operators use a combination of brains and hands-on work to properly transform a metal casting into a valuable working machined part.
As its name clearly states, CNC (computer numerical control) is automated control of machining tools using a computer. Yet, that doesn’t just happen; it requires the right coded programmed instruction.
So, what is G-code? What is M-code? And how do G-code and M-code programming actually work? This article explains each one, but first let’s touch on what programming actually is.
There’s no arguing: CNC machines are incredibly accurate. Their ability to precision cut ¼ the width of a human hair (0.001”), makes them essential in any modern machine shop.
The goal of modern CNC milling is to transform materials such as metal castings into finished, usable parts. That goal is only achievable by using incredibly precise CNC milling machines.
Computer software is the brains of a CNC (Computer Numerical Control) milling machine, controlling the machine and automating production to increase throughput with consistent quality. It’s this repeatability that makes CNC machining so efficient and so valuable to both customers and the machinists themselves (see “The Machinist’s Perspective” throughout this article.)
When it comes to high-quality machining, precision is the key to part quality. And the key to making that process cost-effective is repeatability, so every part can be counted on to perform as expected.
What pops to mind when you think of CNC machining?
Metal. Castings. Precision. Engineering. Robots.
Not “inventory management,” huh? Well, perhaps it should. Because nothing gets done within a CNC machine shop without rock-solid warehouse inventory management.
In fact, if a shop doesn’t have exceptional inventory management, you should choose to work with a different supplier. Here’s why …
The precision of a CNC machine is incredibly impressive: cutting to 0.001” (about 1/4 the width of a human hair). That capability may lead those unfamiliar with CNC machining to assume that it is advanced equipment that makes a CNC machine shop perform well.
Not so fast! There’s complexity within a CNC machine shop’s processes that requires dozens of people working in unison. In fact, we recently celebrated how the skilled people within a CNC machine shop really make the difference in meeting customers’ needs and consistently exceeding their expectations.
When it comes down to it, no member of a CNC machine shop team falls short of “must have” status. Most high-end shops run lean and efficiently, with each employee contributing to the shop’s success in important, but different, ways. Let’s take a look!
You may have a great working knowledge of how custom CNC machining works:
Its smart use of technology and cutting-edge equipment and robotics.
Its engineers who help with design for manufacturing and design/fixture building.
Its programmed G-code and M-code, allowing for correct, repeatable part manufacturing.
Its incredible precision to meet strict spec tolerances.
But, do you know how to test a complex CNC part? After all, you need to know that all that hard work and advanced processes are doing their job and exceeding customer expectations. This article explores one important aspect of quality assurance: pressure testing.
There are 3 main ways to pressure test complex CNC parts:
- Air Decay
- Mass Flow
- Air Under Water
