5. Insert cutting edge geometry

CNC: Insert cutting edge and chip breaker geometry selection

Would we cut or a log of wood with a kitchen knife, or a tomato with an axe ?

No ! Because we know that this would be the result.

We however do the equivalent of this every day on our shop floor, when we use inserts without thinking about the cutting edge geometry. Result ? Higher cycle time, lower product quality, higher tool costs.

The cutting edge looks the same on all inserts, and the fancy pattern on the insert looks like it is just for aesthetics. However, these are the equivalent of the axes and the kitchen knife – they are different for different workpiece materials and applications (roughing, finishing, etc.).

Just understanding this document and selecting the correct chip breaker geometry can dramatically improve the productivity and quality in your CNC machining.

Brilliant packaging, nice food.

I had ‘Nungu’ (called Tari in Hindi) in Coimbatore. I’ve eaten it numerous times before, but never this way, with such nice aesthetics.

Nungu is the fruit of the Toddy palm tree, and Neera is the juice that is collected by tapping new shoots. Neera is sweet when freshly tapped, ferments and becomes the sour alcoholic drink Toddy by evening.

Here the nungu was cut into pieces, served with the Neera in the leaf of the tree. Usually the fruit and the Neera are had separately. Vast improvement over serving the Neera in boring and eco-unfriendly plastic glasses.
