I am looking for Lathe Cutting tool parameters for CNC

(I have posted this question to CCED, Dolphin, and Sherline. I will share
what I learn accordingly.)

I am working on a CNC Turning for use with my Sherline CNC Lathe. I happen
to be using Dolphin, but my question applies to any system.

The Dolphin Partmaster (and any other CAD/CAM) system requires the
definition of the tools that are to be used so that the cutting paths can
be generated. I am working with the Dolphin Turning Module. The code that
I generate will be used on a Sherline CNC Lathe. (It could be any CNC
lathe, but that is what I have).

MY REQUEST FOR HELP:
I need help defining the turing tool parameters, so that I can enter them
into my CAD/CAM program. Vendors sell tools and will usually mention one
angle, but they do not provide the details, such as tip radius, included
angle, width, or cut depth. (Am I making this harder than it needs to
be?)

MY GOAL:
To define the parameters for each of the tool types shown below.

-Eric

DETAILS:
Dolphin Partmaster Turning Module recognizes 5 standard cutting tool types
as I have shown below. In the setup screen, there are up to 7 parameters
that are required to define the given tool. I need to work out the tool
parameters for the standard Lathe tools that Sherline sells.

I would appreciate any help offered to "Fill-in the blanks." Once I have a
complete table, I will share the results with those interested.

Here are the 1/4" shank Lathe cutting tools that Sherline sells:
11920 Carbide Tip, Right Hand Cutting Tool
11930 Carbide Tip, Left Hand Cutting Tool
11940 Carbide Tip, 60 Degree Cutting Tool (I assume this is for
threading)
11941 Carbide Tip, 60 Degree Cutting Tool with 1/64" nose radius for
profiling
11950 High Speed Steel, Right Hand Cutting Tool
11960 High Speed Steel, Left Hand Cutting Tool
11970 High Speed Steel, Boring Tool
1200 High Speed Steel, Internal Threading tool, 1/4" Minimum, Right Hand
30860 Cutoff Tool 0.040

There are also several VALENTINE insert tools. If anyone has the specs on
these, I will add them to the list.

Here, in row/column format, are the tool types and the various parameters,
along with their default values.

My goal is to create a table like this one, but with the parameters for the
above tools.

* TREPAN - This is a term which refers to a Face groove on a Turned Part as
opposed to a normal groove which is achieved by plunging the Groove tool
into the diameter of the part. A TREPAN is achieved by plunging the tool
into a Face on a turned part. I think most people these days refer to a
Trepan as a Groove or Face Groove.
