VB and the development of wizards / Lathe - Maintaining Z axis feedrate

« on: July 28, 2015, 10:10:48 AM »

Does anybody know of a macro to maintain feed rate on the Z axis, no matter what the X axis is doing.
Mach3 maintains the set feed at the tool, so as the X axis speeds up around the arc, the Z axis slows down, reducing the pitch of the thread.
The purpose being to screwcut on an arc segment.

Any suggestions would help with an existing macro (or similar macro to adjust).

Thank you.

If you mean this or similar then - Yes.

Tool entered as turn, lead angle 0, Inc angle 0, Radius 3mm, Z offset 0, X offset 0, Max cut Whatever, Cut side right (or left).
Dxf profile as required offset in cad 3mm out. (both profile are visible, but finished profile is masked a bit by the blank).
The outer profile is selected.

The result is shown in EZ1.jpg, cut perfectly to the required profile, except in corner (EZ2.jpg), that shows the 3mm radius on profile.
With the controlled point set to the Radius centre, this is what you will get, exactly as shown in simulator.
All done in seconds after opening the dxf - EZ3.jpg (and a quick manual facing cut added at start).

I hope this is what you want. (Works for me!)

Thanks Rich - I think the note will do the job.

The older files are finished with, happy for them to go, but hardly worth the effort, unless you need the space.

This is the latest version (at 26th June 2015) of Ezilathe, Version 1.4

This update includes many bug-fixes, and improvements, including Recent files dialog and Zoom window in simulator.
Many Bug fixes especially in the Imperial mode.

After the download is complete, extract the files (Both the exe and the chm files and the two sample directories) to C:Ezilathe.
If an existing installation, your original datafiles should remain usable.

For a new installation, as a minimum the file Materialm.txt from either sample directory is also required.
The other files in the sample directory are user data (a good starting point), just select from imperial or metric.

These files have been scanned with McAfee, and are Virus free. The updated PDF to follow.

Locomobile - Not sure when the next update will be available, Plenty to do. However if you wish I could send it to you direct (This + a few other bugs fixed) if you send a Personal message with your email attached.

The feeds in imperial were being covered by my 16 inches/min max feed under the lathe specs, that was also being read as millimetres. This is fixed in the next update (also warns that speed / feed is at Maximum for Lathe).

Toolchanges, yes already decided, hopefully will suit all. Program will optionally adds M6 between tool command and the comment - e.g. T05 M06 (Right hand face tool).

Other work is being done to improve some areas of the program (I never liked the Zoom in/out commands, I prefer Zoom Window/Extents etc. much easier).

Locomobile - Thank you for the feedback.

Bugs - It's me, needed something small but positive, so I picked 0.1 (thinking mm not inches) as being the breakpoint. Fixed for next upload as 0.0001 min dia.
Speed 3 RPM at 0.08" diameter, Seems ok here (refer attached Jpeg). A value in the override box (above speed box) could effect the value, or Max spindle speed for the selected lathe. Also the Materialm.txt file could be corrupt (Try reload from the metric samples directory, as is the same file as imperial sample).
If none of the above, a screenshot may help me if possible. Looking at the feeds displayed, I appear to need to check these as well (Look a bit low? I should check out Imperial mode operation a bit more).

Also, while I am here, do I need to support people with Auto tool changers, by putting in the odd M6 somewhere, or is it enough just for the user to change the tool selection field from (for example) "T0505,(Facing Tool)" to "T0505,M6 (Facing tool)" .

Richard, Thank you for your response.
The problem could be my shorthand - C:\Ezilathe (note Z not S in the name). You need to create a new directory Ezilathe directly off the root directory of your C: drive. The backslash is only the separator between directory levels (C: and below this Ezilathe)

To do this :-
Open Windows Explorer, and make certain that the navigation pane is visible (Go to View menu-Navigation Pane, and "Tick" the box)
In the navigation panel, select/highlight your C: root drive (usually shows as a name followed by (C:)
Right click on it, and a pop-up menu will open.
Select New from the pop-up and select Folder (Usually the only option here)
This should now create a folder down the "tree view" called New Folder.
While this is still highlighted, rename it to Ezilathe.

After all that copy the contents of the metric sample directory and the Ezilathe.exe, and ezilathe.chm (Help file) to the Ezilathe directory and all should be good.

Spend a little time setting up the program's setup data and you should find it useful.
