Howdy chipmakers, Well -- here is still another version of my "threads" program. This one was prompted by some questions comparing the results with tables from _Machinery's Handbook_. The differences were from comparing my output for Sharp-V threads with tables computed for formed threads. So -- now the program displays all values in table form. The examples follow: ====================================================================== >threads 16 For a thread of: 16.00 TPI the pitch is: 0.0625"/thread | Thread Style Format | Sharp-V | Formed ================================================================ The single depth is: | 0.0541" | 0.0406" The double depth is: | 0.1082" | 0.0812" The 29.5 degrees angle feed is: | 0.0622" | 0.0466" ====================================================================== >threads -m 1.25 For a thread pitch of: 1.25 mm | Thread Style Format | Sharp-V | Formed ================================================================ The single depth is: | 1.0825 mm | 0.8119 mm The double depth is: | 2.1650 mm | 1.6238 mm The 29.5 degrees angle feed is: | 1.2437 mm | 0.9328 mm ====================================================================== >threads Usage: threads TPI or threads -m pitch ====================================================================== Note that you can get a reminder on how to use it by just typing the program name with no arguments. As before, this is as I compiled it on unix, and someone else will have to produce the version for MS-DOS. The executable is for SunOs, but there is a Makefile for compiling it on linux systems as well. (One or the other should work for most unix systems.) The file name is threads-3.tgz (a gzipped tar file), and this file is threads-3.txt (I'll post this file, as well as uploading it to the dropbox as documentation. Enjoy, DoN.
