Re: Where to Set Feed Rates?

Thanks for the reply Ken. Chipload is the key ingredient. Find out from the cutter manufacturer what is a reasonable chipload for your cutter. If you cannot find it on your cutter manufacturer other manufacturers are going to be about the same. You should use a 1 or 2 flute cutter - don't use 4 flut...

Re: Where to Set Feed Rates?

Correct feeds and speeds MUST be determined by the operator. Yes there are some settings in Vectric but they are not specifically designated for your machine or material. They are just some numbers to fill the spaces. I don't know how those numbers are derived. Thinks to learn about and consider whe...

Re: Drilling and Carving Issues

I was not even thinking of non center cutting end mills. I don't think the machine would plunge 2 holes.

Even center cutting end mills don't really have enough gullet clearance for that sort of plunging.

Re: Drilling and Carving Issues

OK,

I looked around the Stepcraft D840 on the web site. Looks like the Stepper motors are .5 newton meters or 70 oz-in of torque.

I just don't think you have enough power to be plunging those holes the way you are doing.

Slow down --- AND --- rethink your hole making strategy.

Re: Drilling and Carving Issues

I don't think you are retracting too far. After the tool change the Z moves up pretty high - plenty of room. I see a pretty fast plunge, pull up then plunge again and again. Then I see the last plunge where you go hit the ESTOP. There was no retract and the machine was moving to another location. I ...

Re: Caveat Emptor: Negative Calculations with Fractions

Makes perfect algebraic sense, but to anyone that is a bit math challenged it is easy to imagine how that would seem a bit sideways.

Good on you for posting that.

Re: Fastest cut speed

When I was buying industrial machines for the workplace, what we were most concerned with was repeatability and reliability. Price found its own place. On my last job, the last machine I bought was a Studer S33 cylindrical grinding machine. I needed to hold something in the neighborhood of 20 millio...

Re: Fastest cut speed

I can cut at 500-600 and possibly faster. Heck, I can most likely cut at 800 if I really wanted to. ---- BUT ---- I do not. Just because I can does not mean I am comfortable with it. Also it depends. It depends on a LOT of things. The list of - it depends - is a long list and I will not even attempt...

Re: Question about V-Bit

I got the setting that Amana has for Vectric tool Data base. Here is a screen shot of there settings Amana Settings.jpg The settings look "reasonable" - even to the conservative side. If you put the number of flutes in the box asking for that, Vectric has been so kind as to calculate the chipload f...

If you use a REALLY good quality marine paint, you don't need the spar varnish.
