Thank you very much for your feedback. It is great to hear you like our films. We are currently in the process of finalising some new films which will be available shortly so keep an eye out for them.
Thumbs up for all the videos you've uploaded allready! It's allways explained in an easy to understand way and the accent of the guy explaining is neutral (which is important to me as i'm not an english speaker and sometimes the accent makes it hard to understand...). Keep up the good work and thanks!!!
Climb milling is the preferred method. The only reason to use conventional milling is for shoulder milling with big ap when there is a high demand on straight walls. With convential machining, using solid cabide tools, the cutter will bend towards the machined wall and will be supported by the wall and as a consequesnce, the bending will be reduced.
My question is why not go full depths and slow down the cutting speeds on full slot milling? I would be worried about tool pulling out on Inconel though I’ve never cut the stuff. But would preventing excessive heat build up be sufficient for the productivity of the tool life. Also this tool could have lasted twice as long at full depth. Not trying to take any credibility from the video but It’s my trouble shooting methods that lead me to believe this. Focus on the problem and eliminate it
Hi Carlos! There are many reasons why applying the tool at full depth and full slot with a reduction in cutting speed will be problematic. In the video you will have noticed the heat build up in the swarf chips, this is partially due to the cutting speed, but equally due to the full radial engagement of the tool. If we consider the type of tool geometry required to machine a full slot, it requires a deep and wide flute to provide sufficient space for the chip that is generated, this in turn means that the core of the tool is relatively small and potentially weak. If we compare this to the preferred tool geometry for trochoidal milling, the flute can be shallower and narrower due to the smaller chip produced, this means we can have a bigger and stronger core, providing greater stability and strength. We can also increase the number of flutes, thus enabling us to increase table feed and metal removal rate. The secret is to achieve maximum metal removal, whilst keeping the heat generation to a minimum. Inconel is a Nickel based HRSA (Hear Resistant Super Alloy) and the heat produced during the machining operation will not be absorbed by the component material, so it will be absorbed by the cutting tool and coolant, which should always be applied (not shown in the video, as the mist would obscure what you see). With reference to tool pull-out, the corkscrew effect, this has and can be problematic, but modern tool-holding chucks eliminate this. Finally, with many machine tool builders adopting a “fast & light” philosophy when developing new machines, we now see machines that are more agile with faster machine spindles, lower power consumption and smaller machine spindle interface including ISO30, ISO40, HSK63 etc. In parallel to this, we have seen a huge development in CAM software. If we put the two together the theme is to take small cuts using smaller tools at faster speeds and table feeds, where the process is faster, quieter and above all more robust to support more autonomous lights out machining. To this end Trochoidal milling or HFSM (High Feed Side Milling) as it is also known, makes it the preferred solution due to the robust process and improved productivity. We at Sandvik Coromant would be very pleased to explore this machining process with you further and demonstrate this in a real life environment. We thank you for your question and have a nice summer!
Maybe in this video, but not in real life. Air time is done with rapid feed, so depending on machine and CAM it is low compared to material engagement time.
Believe me these vdos r really helping for mechanical enginners. Thanks sir 🙏

Tool management and optimizing tool life in relation to productivity is a tool that most shops need to develop.

@CNCconventional The mill is rotating clock wise, which generates a chip that goes from thick to thin, which we recommend.

Very good videos! I really like them, keep up the great work and hope to see your new videos soon!
My left ear enjoyed this

I wish each video was 3 minutes of explanation!
👍
run Trumill and swiftcarb end mills ramping up to 15 deg.
air time = cutting time . it is no good
