This is the first lecture of cutting course in which educator discuss about meal cutting operation introduction part and some input parameter that will used in that metal cutting

Introduction and Input Parameter (in Hindi)

This lecture is tells all about terminology used in metal cutting like rake angle uncut chip thickness, chip thickness, shear plane, shear angle, clearance angle etc and different types of force apply on tool

Mechanics of Metal Cutting and Forces to Tool (in Hindi)

This lecture tells about difference between orthogonal cutting and oblique cutting. Also we cover advantages and disadvantages of orthogonal and oblique cutting with their uses in different machines

Difference between Orthogonal Cutting and Oblique Cutting (in Hindi)

This lecture cover tool signature according to ASA system in which all six angle was cover with nose radius how they made and denote.

ASA Tool Signature and Different Angles (in Hindi)

This lecture tells about back rake angle that used in tool with three different types positive zero and negative . educator discuss when and why these different back rake angles is used

Back Rake Angle- Positive -Zero and Negative (in Hindi)

In this lecture educator discuss some important derivation of relation that is used in metal cutting

Important relation with their derivation (in hindi)

Relation that we drived in past lecture is very important so by the use of these relation we r going to solve some numericals in that lecture

Metal cutting important numericals (in hindi)

This lecture  is about types of chips in which educator discuss all 3 types of chips and their favorable condition and their effect all 3 types of chips are continuous chips, discontinuous chips and continuous chips with build up edge.

Types of chips- continuous, discontinuous and build up edge (in hindi)

In analysis of cutting we derived formula for this thickness ratio. Also we study chip reduction factor. drive and learn two formula that was very important.

Analysis of cutting: this thickness ratio derivation (in hindi)

In that lecture we will discuss shear strain or cutting shera strain and their derivation also we cover velocity ratio and their relation with derivation then we discuss chip thickness ratio in terms of length

Cutting shear strain, velocity ratio and length ratio derivation (in hindi)

Till previous lecture educator discuss all about the formula and their derivation. So today in that lecture by the use of these formula we are going to solve some numericals.

Numericals on cutting process (in hindi)

Force analysis on tool is very important topic in metal cutting. For the force analysis first we have to do merchant's circle analysis.by this analysis we are able to find all forces used in metal cutting

Force analysis: marchant's circle (in hindi)

After study of force analysis by marchant's circle we are going to study power analysis in cutting process. Also we are going to see different theories that can be used to solve the numericals.

Power analysis in cutting and different theories (in hindi)

Material removal taye and specific cutting energy can be calculated bu given formula. Some numericals is there to understand the concept.

MRR and specific cutting energy with numericals (In Hindi)

Force analysis on cutting we study earlier lecture. Marchant's circle is the best approach to calculate different force on tool so different force calculation numericals can be solved by marchant's circle approach. These numericals are cover in that lecture

Numericals on cutting with marchent's circle (in hindi)

Heat generation in cutting is very important in cutting process because it cause tool wear and tool failure. In that lecture we discuss heat generation and some numericals also

Heat generation in cutting and numericals

Numericals on cutting

Tool wear and tool failure are very important in cutting .  Because it cause more power consumption and poor surface finish.

Tool wear and tool failure (in hindi)

Crater wear and flank wear are the types of wear. In that lecture we are going to study these two wear.

Crater wear and flank wear (in hindi)
