CNC Machinist Calculator Functions
CNC LATHE TAPER
Calculate chamfers, taper, & radii. Then export the g-code for your CNC lathe. Export corner rounding g-code for internal & external chamfers, taper, & radii with tool nose compensation.
CALCULATE CUTTING SPEED
Calculate cutting speed for turning, milling, & drilling. Choose from over 180 different types of material. Choose cutter material type (Carbide or HSS) & fine tune by setting the material hardness. (App shows hardness limits for each material)
TAP DRILL CALCULATOR
Tap drill calculator for both roll form and cut taps based on your required percentage of thread.
Cusp height calculator, Radial chip thinning calculator, Effective diameter for ball end mills, IPT to IPM conversion, Cutting speed calculator, SFM to RPM calculator
Get thread pitch, major, minor, root radius, helix angle, and more for 60° threads. Shows min and max wire sizes for checking each thread and shows the correct measurement over pins for whatever wire size you choose. Contains UNC, UNF, UNEF, UNS, UN, UNM, UNJ, & M profile threads. UN threads up to Ø4" & M profile threads up to Ø600mm
Groove & cut off cycle time calculator, Roughing cycle time calculator, Turning SFM calculator, SFM to RPM conversion tool, IPR to IPM conversion tool, IPM to IPR conversion tool
THREAD PASS CALCULATOR
Calculate thread passes in turning. Also calculate helix angle, thread height, & more..
Calculates angles and sides of both right & oblique triangles. Just enter any two values for a right triangle or any three values for an oblique triangle.
TRUE POSITION CALCULATOR
Calculate true position of a feature based on the distance from zero in the X & Y axis
CIRCLE SEGMENT CALCULATOR
Calculate angle, radius, arc length, chord length, tangent length, middle ordinate, segment area, and sector area of a circle segment.
SURFACE FINISH CALCULATORS
Calculates lathe surface finish based on tool radius and feed. Calculate mill side wall finish based on tool diameter, cutting edges, and feed rate. Calculate step over distance of ball end mill based on your required surface finish. Convert Ra finish to other common surface finishes such as RMS, Rp, & Rt.
Calculate cutting speed, feed, & cut time based on drill diameter, tool material, and depth. Also calculate drill point length based on tool diameter and drill point angle.
Calculate Sine bar block height. Calculate circular segment features. Calculate area, radius, & circumference of a circle. Calculate the diameter over a hex & diameter over the points of a square.
Convert degrees, minutes, & seconds to decimal degrees and vice versa. Convert fraction to decimal. Convert inch to metric. Convert surface meters to surface footage.
