IHarmonizer is a free application for recording machining noise, saving the file, and sending it to MLI for a free evaluation (send to harmonizer@mfg-labs.com). If the user desires he may do an "in-app" purchase to do the evaluation immediately and on site. The program detects chatter and suggests alternate spindles speeds to possibly eliminate the chatter. It also will terminate and indicate if there is no stable spindle speed to be found. Please contact harmonizer@mfg-labs.com for any questions.
