Mill Tapping G code Generator

I just cobbled up a python script to generate G code for drilling and tapping on a mill. Remove the .txt from the file name before using. If you open this up in Axis you can send the code directly to Axis.



NOTE: we are working on adding metric support so for now don't try using metric in units as it will be wrong.

Version 0.3.0 Added some more goodies. Metric still not fully functional. If someone wants to convert the dictionary from inch to mm this would complete this app.

Version 0.1.0 added metric drill sizes but dictionary needs converting
Version 0.2.0 added support for G83
Version 0.3.0 added F1 key binding to the help screen and changed the Tkinter import

        # Metric Drills change inch drills and pitch to metric and your set
        # tap size, pitch, 75% drill, 75% drill diameter, 50% drill for steel, 50% dia

Hi John,

I couldn't download that last attachment. I got an error: "Internal Server Error" 404 error

I did download the earlier version, but for the life of me, couldn't input coordinates into your self.CordList Listbox.

I like the concept that you have going on.

Dan,

To add an XY pair to the list box you start in the X Center box, type in a value then press Enter. This moves the focus to the Y Center box. Type in a value and press Enter, this adds the pair to the XY List and moves the focus back to the X Center box for the next entry pair.

This is an adaptation of my counter bore program and I've attached the latest version 0.3.2.

0.3.5 fixed a typo and an omission that caused an error if you left the peck depth field blank.

Rob converted the metric dictionary last night so I'm adding metric fine and coarse to the generator. Oh and I'm adding G82 spot drill too.
