Machinist calculator Use it every day. Very handy for angles and hole circles. I am a factory maintenance and die repair man and appreciate this apps simplicity. Machinery handbook is gathering dust.
All good Pitch circle diameter I find very useful.
Perfect I use the trig and sine bar functions everyday. Only problem is my phone gets filthy from using it so much.
A good app for any machinist. I use the sine bar portion of this weekly. That alone is well worth the few bucks I paid.
Great app Simple and easy to use.
Work's good The only problem is just application icon just shows an Andriod icon with Words Machinist calculator under it.
3 Wire Thread Measure Function Added
Quickly make all the calculations required to measure screw threads using the 3 wire method!
Whitworth (BSW), UN, ISO Metric, Trapezoidal, Acme, and Stub Acme. Uses formulas that give very accurate results for lead (helix) angles generated by single start threads. When measuring threads with larger angles, such as UN or ISO Metric, results will be highly accurate for threads with lead angles up to ten degrees.
Calculate speeds and feeds for drills, milling cutters, and lathe workpieces.
Calculate precision block stack or angle for use with sine bars or sine plates.
