Machinist Helper

Description:Calculates thread data for Unified, Metric, Acme, British Standard Withworth and NPT threads. It uses Buckingham Involute Helicoid formulas for calculating Measurements over wire for all threads except NPT. The Triangle Solver can solve right or oblique triangles. The Circular Segment Solver and Polygon Solver are integrated. The Bolt Circle Solver can also solve equally space holes on an arc. The Feeds and Speeds Solver also calculates chip thinning for ball or flat end mills. The unique Taper Solver will solve any taper problem and can measure taper diameters using a ball diameter. It has a Keyway Solver for shafts and hubs. The True Position Solver calculates using RFS MMC a or LMC and can tell you if your holes locations are accepted or rejected. A companion to this is the gage block stack solver written by David Hayden.

I got tired of hearing machinist talk about how great the Machinst calculator Calc-Pro is. As a machnist, and a log time HP calculator user that didn't rub well with me. Machinist helper 1.3 in my opinon is a much better program than Calc-Pro. Calc-pro is a scientic calculator while HP50 is a graphing calculator, no comparison.

There is a problem. In the triangle solutions, there is sss, ssa, sas, saa, but there is no solver for asa. You forgot one.

Sorry,It only works on a HP50 calculator. It sure would be niece to have Machinist Helper ported to the HPPRIME.
