- Join In The Loupe TV's "Cutting Tool Counselor," Don Grandt, as he brings you through the ins and outs of Helical Interpolation, the most efficient way of reaching the bottom of a hole. Learn how to save time at your spindle as Don explains the key factors to making Helical Interpolation possible! From ramp angle, geometry, and pitch to proper speeds and feeds, this episode will deliver you the knowledge needed to take your application to new levels.

How to calculate what pitch we need to interpolate at.
I am interpolating a 125mm dia, 8 tipped high feed paramet cutter into the casting with 145mm hole to bore it to 152mm. The feeds and speeds are calculated but really confused about increment of Z into the bore. I tried same cutter same feeds and speeds for a bigger bore in the same casting which is about 180mm and used an increment(pitch) of 0.5mm per lap but the same increment is not working for 152mm bore. Could you please explain how to calculate that?
I absolutely LOVE these videos! You fit right into where I'm trying to Excell at in my life right now! I have machining advisor pro at work and I thought it was a gold mine when I found it! I am assuming that you guys have a big part in that since the tooling offered is helical as well? Keep these videos going please because you are hitting some of the key information I'm looking for currently!
This episode prompted an episode idea from me, even BEFORE you said the quickest way to the bottom of the hole is to drill it. I've heard time and again that drilling is the fastest way to remove material, but I don't know much about practical application. I imagine drilling a hole pattern in a pocket area... but what kind of drill? Can you overlap holes, so to speak, with the right tooling? How do you deal with all the webs left between the holes? Is finishing the pockets really that much faster if the bulk of the material was removed with a drill? Sure, now there is less material to remove, but radial engagement is going to be constantly varying, how do you calculate the most efficient way to get rid of all that without breaking the tool with a spike load? Related, what exactly is the difference between drilling and plunge milling aside from the geometry at the end of the tool?
In the Cue sir. Great suggestion on the Drills. We are planning on branching to other Specific cutting tools.. Thanks for Watching and Keep an eye out for your episode!!
I feel some of your videos really only apply to a lot of your tools. I'm a big Fraisa guy. I use some of their 4 flute end mills and ramp at 9-10° in Titanium all day long at decent feeds (probably even on diameters small than I should). All depends on the tool is my point. Still a great informative video!
Awesome video! Can't wait for the surfacing video! Hope we can dive into scallop height etc.
Controlling Scallop Height with your tools is a great subject. Hope we can do it justice! Thanks for watching and following.

Awesome info! Thank you. Was 9:50 a jab at titan? :)
I respect all of the influencers in our industry.. Titan does a great job with his content. Nothing but Love! lol CTC
When does it make sense to helical mill a hole instead of drilling? Most of our machining is in soft copper. I need to find the fastest way to make a hole with the least amount of burr where the tool breaks out of the bottom of the material. Is it ever more productive to helical ramp than to drill and then finish with an end mill?
If you are trying to get a burr free hole I would suggest Helical Ramping over Drilling. That being said there are several Material specific Drills that will help eliminate the burr on exit. An endmill will clean up the hole very nicely with a helical interpolation on your exit hole. CTC
Informative content. Worth the watch. What i'd like to see for future content is a discussion on lead in / lead out. CAM software has options for various lead parameters angle, radius, vertical, horizontal, feed, speed etc. I haven't a seen a good description of these from a tool perspective.
I have just completed a Vlog with Mastercam on some programming tips for our CTIC video.. I would love to get with them on this subject and bring a detailed ( Fun) video for our followers. Look forward to diving into this for you from a cutting tool Perspective. Thanks for watching!
Blue's clues 😅
You never told us about pitch angle settings for different materials and diameters.
Thank you

0.8 is 80% and not 0.8%
Yes you are correct.. That's why I put the multiplication on the screen. Meant 80% of diameter or Multiply by .8. Thanks for paying attention! LOL
Thank you so much for making such effort to explain it clearly. Couldn't wait to see your other vids.
I'm looking for some info on how to properly use 'debur' bits (vs. chamfer). Are the tool paths the same? Great content here. Keep up the vids.
With the relationship with our CAM partners and the variety of Lolipop and Chamfer cutters we carry, this will make a great episode! We can dive into creating those paths and using these tools. Keep an eye out for it! Thanks for watching...
Keep on making em.
That's not interpolation, it's orbital milling. Interpolation uses a single point cutter with it's edge at a constant angle to the cut. Think of using a deburr whip.

Thank u don🙏...
NO thank you for watching.
9:31 This is the truth. I'm tired of hearing about tools that can rip at crazy feed rates. I know they can, but I'm looking for a good combo of longevity and speed as someone who is relying on running lights out.
Amen!!! Sustainability!
