Do you do your job as fast as you want? Do you struggle to keep up with deadlines and production goals? Or, are you the proactive thinker, always looking for smarter and faster ways to do the job, without sacrificing quality?
Whatever the case, you can boost your speed. See if implementing any of these tips will help you:
Optimize Your Cut Depth and Width
This is tough to do manually. You can spend years trying hundreds of combinations, or sticking to a rule of thumb. But, the problem with that is you might miss out on the optimal cut depth and width for a certain project anyway.
These days, you need to rely on software. It can quickly run hundreds of comparisons for you and find the optimum cut depth and width so you don’t have to spend years trying to find them on your own.
What to Do When Your Feed Rates Aren’t Fast Enough
You can experience this issue when cutting soft materials that have big chip loads. CNC router users see this problem the most frequently of all CNC machinists.
Fortunately, it’s easy enough to work around. If you’ve maxed out your feed rate, slow down the RPM on the spindle. This in turn reduces the feed rate necessary. You can also try using a smaller cutter, and that will give the added benefit of a lower chip load too.
Finally, you can also try reducing the number of flutes on your cutter. Going down from a 4-flute cutter to a single flute gives you ¼ of the feed rate. Exceptions to this rule exist for sticky materials, but you can ignore that for now.
A Few Other Techniques You Can Use
There are a number of “high speed machining” techniques you can use to increase your speed. You can combine the rough and finish passes. Use smaller tooling because it generally moves faster. Use a cut width of 5-15% of the tool diameter because it allows the tool more time for cooling down. Also, use tool path strategies that avoid the loss of productivity cutting corners can cause.
