Rake Angle (+Ve, -Ve & Zero ) (हिन्दी )

[@brijendrabunkar9406]

nice explanation brother. thanks

[@LEARNANDGROW]

Glad to help you

[@ekrushnaMurty]

Clear Video sir.
Please tell that high Rake angle means positive or negative rake angle?

[@nikhilkumarsao1562]

Zero back rake angle used for thread cutting operation and machining of brass work piece.

[@Just1Clown4.0]

Makers of #LearnAndGrow can u make a video, explaining this.

[@tarunasharma4207]

Thank you sir , I had confusion and didn't get the concept but aapki vedio dekh ke bohot ache se samaj aa gaya

[@LEARNANDGROW]

Glad to help you

[@sameertoppo6100]

Zero rake angle provide for cutting brass when cutting by hss tool

[@rutujamore2786]

sir you are great teacher.....

[@LEARNANDGROW]

Thank you for your motivated words

[@sreeharimw1753]

Bro will the contact length increase or decrease with increase in positive rake angle

[@ABHISHEK-IITPATNA]

your work is great sir.

[@LEARNANDGROW]

Thank you for your precious and motivated words

Bhot hard sir jiii.... 😍

[@rameshsankhat9334]

Sir , (+ve) Or (-ve) rack angel material ke hisaab se kitna hona chahiye?

[@vimalbolozubankesri8996]

But negative rake angle is used to avoid built up edge but u said that in positive rake angle does not produces built up edge explain please

[@pithirajdasgupta9701]

in ur another video u have said larger negative rake is provided for continious chips flow ...but in this video u are saying that positive rake angle is provided for continious chip flow ....not clear plese explain clearly sir ..I m waiting for ur answer

[@LEARNANDGROW]

Brother, this will depend on material.if we work on ductile material.Then continuous chips will form in both negative or positive rack angle.but CHIP force on the tool will different.
Thanks

[@pithirajdasgupta9701]

.thank u ..:-)

[@sachinkatiyar7691]

in ceramic and carbide material negative rake is provided because ceramic and carbide are brittle material, brittle material is strong in compress and weaker in tension .with positive rake when chip flows a normal force will act on rake face and broke it and with negative rake this normal force will act as compression froce so no failure . but negative rake required high cutting velocity so a impact will act on tool due to high cutting velocity. thats why only insert of negative rake is user remaining part of tool is made of HSS which is ductile material and can wear impact without any failure .

[@kurianauto645]

Very good concept.
