How LatheMate Delivers Shop-Floor Results

LatheMate Cutting Calc eliminates guesswork from lathe operations by providing instant RPM calculations based on material type and workpiece diameter. Select your stock—Acetal, Aluminum 6061, Brass C360, or any of 15 other metals and plastics—then choose HSS or Carbide tooling. The app instantly displays recommended spindle speed with surface footage context, so you know exactly where to set your lathe dial before the first cut.

Threading operations become streamlined through the dedicated wizard interface. Input major diameter and pitch for metric threads or specify TPI for imperial 60° V-threads. The calculator returns tap drill size, thread depth, compound rest angle, and safe threading RPM—all the critical dimensions for clean, accurate threads. Save frequent thread jobs to your library for one-tap recall during repeat setups.

Taper cutting setup takes seconds with preset Morse taper standards MT0 through MT5, plus custom taper angle calculation. The converter tool handles fractional inch to decimal and millimeter conversions with nearest-fraction lookup, eliminating measurement errors. Every calculation runs offline, so network dropouts in the workshop never slow you down.
