kind of important to know whether there is 20 or 2000 lbs of force on a part if you want to be able to hold the part securely. thus i can scroll down the tool list and see the range of settings tried for a particular tool setup (tool length is a very important factor on limits) and see the limits where sudden tool failures are more common.Īlso in row i can enter depth and width of cut and machinability rating and calculate hp power requirements and cutting forces. i record any sudden tool failures and date and any data i feel important. I use a excel file with all tooling (over 5000 tools) i use and every setting tried, each different in a row with formals.

and of course there are books that can be bought on Microsoft Office too assuming they dont teach it in any school you have been too. there are tutorials on the basics on the internet as well as the help system found with many programs. fairly common in many shops to be using Excel and Powerpoint. Powerpoint can within seconds take a picture of a machining setup and you can add a arrow and a text box to point stuff out. you can enter a math formula and leave cells where you input data like diameter and sfpm and ipt and press enter and it calculates the math formulas.īasically its a calculator you can leave the formulas in or on a work sheet so like a programmable calculator but better you can leave the formulas on a work sheet and just change certain cells for entering diameter and sfpm or what ever you want.Įxcel and Powerpoint are often taught in schools now as they are useful for many jobs.

look at tooling you have the name brands and info on box and look them up on the internetĮxcel which is part of Microsoft Office and Calc which is part of free Open Office and Libre Office pretty much do the same thing.

and vast majority are free and on the internet. Tooling catalogs of drills and mills and lathe cutting tools are full of math formulas and speed and feed recommendations.
