The higher then number for MRR, the better. Width of cut x Depth of cut x Feed in Inches Per Minute = Metal removal rate in cubic inches per minute
For this you must calculate the MRR, Metal Removal Rate, of the toolpath. These make for great stories but don't show overall efficiency. When trying to push cutters to their limits, some often get caught up in high feedrates and spindle speeds. When using HEM, you will be limited to only a few selections for the stepover percentage whereas with RCTF, you can define any value you want. Mastercam displays the corresponding feed rate and spindle speed values below the field. When you enter the maximum HEM Factor allowed by the machine and tool configuration, Mastercam displays a message marked with an asterisk and marks the threshold value in the same manner.īoth RCTF and HEM are effected by the stepover percentage used in the toolpath.

You can enter a value from 1 up to 5, depending on the selected machine and tool configuration. Having the best software is only one ingredient for success. Enter a value in the field or use the slider positioned directly above the field to adjust it.
HEM Factor - Adjusts the ISCAR tool's feed rate and spindle speed values to achieve maximum speed and efficiency.
