Details are as follows-
W/P material- AISI 4340 hardened steel
Cutting inserts- AlTiN coated carbides
Cutting environment- (a) MQL with 1) Canola 2) Coconut 3) Soyabean & 4) Synthetic oil and (b) Dry cutting.
Kindly guide me regarding the same.
Hi
As well the type of the workpeice and the material of the tool, many factors affect on the values of c&n from which are: machining conditions (cutting speed, feed rate, depth of cut). So it is better to determine these values experimentally based on the real machining process you need.......... Good Luck
Dear Sir. You need to make experimental tests using the ISO 3685 standard. Following the methodology explain in this document you can obtain the C and n values.

As reference, if you want, you can use, for example, this paper:

You can use: n=0.2 & c= 46, but these are an approximated values. It is better to determine n&c experimentally.
Dear all,
Thank you for your valuable suggestions. I will follow the guidelines.
