Open Source BASIC CAD Software for Windows

This Application assists the usage for CNC threading, especially the Mach3 software. The threading cycle uses the G76 command with some parameters. This program lets the user select from hundreds of predefined or free definable thread standards and calculates the parameters for the Mach3 command line. So, essentially just select your thread, calculate it, copy & paste the result to a GCode file, hit "Cycle start" and you get exactly what you want. Also included is a little tool to calculate the pitch diameter of a thread based on a measurement with three wires. Supports the threading standards M, G, R, BSW, BSF, UNC, UNF, UNEF and tapered Pipe R/Rc and Metrical threads. New: NPSM, NPT, NPTF, NPSC, NPSF. Includes an improved version of the Mach3 M1076.m1s threading macro and a matching screenset. Try also the Feed Calculator: www.sourceforge.net/p/feedcalculator

The Feed Calculator is a small program to calculate the feed and spindle speed for turning and milling machines.. The help provides an excerpt of the machining tables which propose cutting speeds and feed per edges for various tools, especially for small machines and modeling. With this data, you can easily find the working parameters for your job on numeric controlled machines. For easier use, you can customize the tool table (number of edges) to your own tool rack.
