The goal of any CNC machining operation is to maximize efficiency. At its core, this means maximizing the number of parts produced per hour and minimizing scrap.
But how do you achieve that? The answer is a combination of factors: Tools, feeds and speeds, machine setup and maintenance, etc. In this article we’ll discuss some methods that can be used when optimizing your CNC machining process for maximum efficiency.
Use High Quality Feeds and Speeds
The two most important things you can do to optimize your CNC machining process are using feeds and speeds that are appropriate for the material, tool and cutter used. Too fast is as bad as too slow. Feeds and speeds are dependent on the tool and cutter used (e.g., a roughing end mill will require higher feedrates than a finishing end mill).
The best way to determine the correct feeds and speeds is by using a CAM program. However, it’s important to understand what each term means so that you can make an informed decision about how your machine will be set up.
Feed is defined as the rate of movement of a cutting tool into the material. Feedrate is measured in inches per minute (IPM) or millimeters per minute (mm/min). In general, higher feeds will produce better results, but only up to a point.
Clean the Cutting Tool
Cleaning the cutting tool is an important step in maximizing efficiency in CNC machining. The cutting tool should be cleaned after every use, as this will help prevent it from becoming worn or damaged and result in better machining performance.
A wire brush or similar cleaning device can be used to remove any debris that may have accumulated on the cutting edge of your end mill during use.
It is important to note that wire brushes can wear out over time, and they must be changed regularly.
After cleaning the cutting tool, it is important to lubricate it. The cutting tool should be lubricated before every use, as this will help prevent it from becoming worn or damaged and result in better machining performance. A high-quality cutting fluid can be used for this purpose.
Maximizing efficiency in CNC machining is a process that can be learned.
Maximizing efficiency in CNC machining is a process that can be learned. It’s not just about the machine, or even the material or tool. It’s about learning how to use them all together to get your job done as quickly and efficiently as possible. Here are some of the best ways to maximize your time and effort:
- Use appropriate tools for each task
- Always have enough stock on hand for material prep before running a job
- Take advantage of tool paths when they’re available (such as nesting)
Learn how to use the machine’s software to its fullest potential. Finally, understand that it’s OK to make mistakes. Mistakes are how we learn and grow as machinists, so don’t be afraid of them!
