People sometimes find it difficult to understand CNC machining in particular. ᴍᴀɴy people assume that CNC is simple and jump into unexplored waters without sufficient knowledge and training. Others will completely avoid CNC machining out of concern that it will be an ᴏᴠᴇʀᴡʜᴇʟᴍɪɴɢ task. The truth is that CNC machining can be very affordable, but before you get started, it’s helpful to know what it is and isn’t. We’ll debunk a few popular myths below.
No Experience Necessary
Each and every machine maker in the market would tout how user-friendly their CNC is. Modern machining centers have a range of tools and add-ons to make the machining process easier, such visual programming systems, automatic tool presetters, high-tech work probes, and others. But in the end, a machine is only as good as its operator, and it takes time to become familiar with the CNC process and the equipment and ᴍᴇᴛʜods needed to consistently produce high-quality parts.
It’s usually preferable to seek assistance from individuals with more experience if you’re new to CNC machining. Most machine retailers offer both online and in-person training. Vendors of tools and materials can assist consumers in receiving correct cutters, feeds/speeds, job holding, etc. Online discussion boards are a terrific place to post issues and look for solutions to problems you might be having. The field of CNC machining is one where there is always soᴍᴇᴛʜing new to learn.
There is a widespread misconception that once a part has been run through a CNC, it will continue to produce high-quality components without any problems. It is true that machine automation has made tremendous strides: Thanks to modern technologies, “lights-out production” is becoming more widely available. However, problems will always exist. Tools fail. Parts move. Inserts deteriorate. Operator intervention will eventually be required to maintain part quality, fix machine issues, or prevent them from happening.
A CNC needs to know what operations to perform and how to conduct them in order to machine a part. In order to connect with the computer and instruct it to carry out its functions, operators used to type in a long string of numbers and letters. Today, most shops use 3D CAM systems to specify their tools, workpiece, cutting paths, drill cycles, and other aspects of their operations. Similar to this, a lot of machines rely on visual programming systems, which let operators program parts by merely adding a few measurements to a library of pre-built milling procedures.
In the area of machine automation, incredible advancements have been made. Large ᴍᴀɴufacturing companies have embraced ᴍᴀɴy of these technologies to boost capacity and speed up production. That being said, without knowledgeable operators and programmers, not even the most robust automation system would work.
