Mill Drill holes are too deep

Mill Drill holes are too deep

Why is it that when I use mill drill for a hole it is always to deep? I specify for a hole to be milled to a depth of .0625 yet in the post it comes out to .1 deep as if it were still adding in extra depth for a drill point or something. This is the only thing I can think of that it might be as it seems to vary with the hole size. Is this correct? is there a way to avoid this? I can't be drilling or machining into my vacuum plate. The only work around I have found is to create each hole as a side which can take a huge amount of time on some parts that can have a couple hundred holes. I have attached a file with just a few holes of different sizes and every size is being machined to a different depth.

What i usually do if I need an exact depth is set the value I want here.

I also use this parameter in such a case and you are on the safe side.

Diesen Parameter setze ich in so einen Fall auch und du bist auf der sicheren Seite.

Yes I use that all the time when I am drilling with a drill, but that option is not there for the mill drilling option.

   I use rough with end mill to full size and all I get is a milling tab. The only option in this tab is the "z" step. I have tried using this, but it just makes it take it in more than one step. So what it appears that I have to do is calculate (or figure out) just how much extra each size drill would go down and subtract that off of the depth. unfortunately the depths don't seem to calculate out exactly as to how far FeatureCam is actually going. so I still have to make the hole see how much too deep it's going by looking at the post and then changing it in the feature.

Okay after a lot of trial and error I have figured out how to stop the holes from milling out to deep. Turns out all I have to do is turn off through hole on the dimensions tab. So not as bad as having to figure out how deep it's going for each hole size. I knew there had to be a way.

The drill milling options are already curious. Anyway, not practice close. Here you need more flexibility and options. For example, you just want spiral finishing, or just spiraling, etc., so you save a tool, etc. The options available are similar to the tools and technology of the Middle Ages, to say the least. Maybe it will be given to the development to revise these options and adapt them to today's tools. Sincerely, Mathias Beyer

 

Die Bohrfräsoptionen sind schon kurios. Jedenfalls nicht Praxis nah. Hier braucht man mehr Flexibilität und Optionen. Zum Beispiel man will nur Spiral Schlichten, oder nur Spiral Schruppen, usw. damit man ein Werkzeug einspart usw. Die vorhandenen Optionen entsprechen den Werkzeugen und der Technologie aus dem Mittelalter, um es mal übertrieben zu sagen. Vielleicht wird es mal an die Entwicklung weiter gegeben, um diese Optionen zu Überarbeiten und an die heutigen Werkzeuge anzupassen. Mit freundlichen Grüßen Mathias Beyer

Yes, I must agree. I can drill mill a half inch hole on my new Datron in half the time if I program them at the machine vs. using FC. when you have a machine that will run at 60,000 RPM. you can take that hole out with one or two passes without the tool ever leaving the material. The biggest problem all the way around with FeatureCam is cutting too much air. This adds a huge amount of time to parts and time is money.
