  1. I have a laguna IQ and this video is just what i needed to set my speeds and feeds. I like the part about reading the chip that is super helpful. A video about how to hold down the wood and various fixturing would be a video i would like to see. Thanks your channel is always helpful and you are a great teacher

  2. It's been a while but this video is still very useful today. congratulations, my cnc is small 1000mm x 800mm with 315oz motors 1605 spindle, I did a test flattening the sacrifice table at 6000mm/min really when the machine can cut within those parameters mentioned by you, it's another level although 6000mm/min was the maximum I could at the moment. here in Brazil homemade machines make a lot of dust ? today I managed to make some grains, and it gets a lot less dirty.

  3. Ok. so I mainly work with laminated chipboards ,my cnc runs at 5000 mm/min because of the vacuum pump capacity(My boss is not open to investing more money). Anything above and I risk the plate being pushed, especially on smaller plates. I use a two flute 8mm carbide compression bit. Applying this formula I get that the optimal rpm's for the designated chip load is only 6000 rpm's?

    Also. I would recommend a starting lead into laminated chip boards with a straight plunge. I was trying the ramps and it always chipped of the laminate at the point of entry off the chipboard which was driving me crazy.

  4. I really do love this video. Could the excel sheet be modified for the hobbyist? I know you said the chip load would be on the lower side of the ranges you have here – might be helpful for a 2nd tab for hobbyist

  5. Amazing, saw on many other videos and sources to slow down the cutting for a better finish. Didn't think to go faster! Guess its kind of like flying, better to be moving fast or you stall out!

  6. Is the hardwood that they speak of your general American hardwoods? Like Black Walnut, White Oak, and Cherry?
    I mean even those have a lot of spread in hardness, not even considering something like IPE or Desert Ironwood.

  7. Been watching your videos and they have helped more than you would imagine. Really like the chip load chart you provided. Do you know if there is one for smaller bits or do you use the same chip load for 1/8? I would think that would be too much for a 1mm or even 1.5mm. If you could help. Thanks.
