Optimal Cutting Parameters for Hard Materials Using Carbide Tools

[nolanmaris]

Hello,

I currently working on aproject that requires machining hard materials like hardened steel and titanium alloys using carbide tools. To optimize the process, I need advice on a few key aspects.

I want to know what are the cutting speeds and feed rates for carbide tools when working with these materials? I am interested in how these parameters might vary depending on the type of carbide grade used.
I would like to know about the effectiveness of coolant in improving tool life for these materials are there special types of coolants / methods of application that are more effective? I have referred https://www.sandvik.coromant.com/en-gb/knowledge and splunk documentation guide but still need help.



Also interested in understanding the common indicators of tool wear when machining hard materials and how I might adjust my parameters to minimize it.


Any tips would be greatly appreciated.



Thank you in advance !

ShopBot does not recommend, support, or advertise that ShopBots will cut steel, but Jens Dyvik is a member of the MIT fablab group and has done all kinds of interesting things with ShopBots including cutting steel:

If you expand the commentary in his video he lists all the settings that he used, and a link to the Rhino plug-in that he used to create the toolpaths. Your mileage may certainly vary.
