Useful Speed and Feed Calculations

    As a new operator, you may or may not understand the importance of speeds and feeds for different tools and materials.  In general, aluminums like higher rpms and steels enjoy slower rpms.  Remember I am speaking in very general terms here.   For example, the surface speed for 6061 AL with a carbide […]

Converting Metric to Standard and Vice-Versa

To convert millimeters to inches, divide by 25.4.   For example, the  dimension is 18.00 mm.  18/25.4=.7086.  So the dimension is  .7086″. Conversely if your dimension is 1.25″ and you need the metric equivalent you will multiply.  1.25×25.4=31.75.  You can see that 1.25″ = 31.75mm. O r you can find a handy conversion app for your […]
