Simple drilling operation

• centre line drilling only
• peck drilling
• canned cycle and simplified* output

Simplified output would discritise canned cycles to individual G0/1 moves for use on a basic controller. This would usually be done in a post processor but it might be a nice feature to build into the library.

Return shape of uncut areas to allow rest machining

multiple finishing passes cause bad path

• allow finishing at a lower feedrate
• allow facing beyond the start of the part

Bug found in #66 means either rewrite or drop support.

Unit tests should be added first. Once complete, integration tests should be added.

Features:

• one shot parting
• peck parting
• peck parting with a one shot finishing pass

Add constant surface speed (G96) as an option.

Review license suitability.

• pecking
• multipass (make multiple passes with a small overlap to reduce binding)

removing the groove fails for arch segments and allows the tool to continue around the arc.

calculate the point on the arc where the normal is == tool max angle

Update existing ''' docstring to python convention https://www.python.org/dev/peps/pep-0257/

LibLathe needs to handle the tool orientation

• -X
  *+X
  *90 deg rotations (e.g. boring)

create a logging module to allow a consistent method to write to a logfile or print debug information

add human unstandable output such as 'Line Element', 'Clockwise Arc' and map the flow through each function:

from inspect import getframeinfo, stack

def debuginfo(message):
caller = getframeinfo(stack()[1][0])
print "%s - %s - lineno %d: %s" % (caller.filename, caller.function, caller.lineno, message)

[filename.py - functionname- lineno xx: message]

If the stock zmax is equal to part zmax, roughing passes fail to intersect with the finishing pass and violate the part segment.

Add python supported versions banner to top of readme.md - This can be done through PyPi API. Need account and release first.

Investigate and add imagedraw.

https://pillow.readthedocs.io/en/stable/reference/ImageDraw.html

Acceptance criteria

• Draw paths
• Class based (Class in the library called LLPlot with a method called get backplot)
• Works with example
• Set the background colour
• Automatically calculate image size
• Set G path color
• Set the line thickness

Review naming convention for methods, method variables (passed in) and variable inside of methods.

Also consider variable declaration.

LibLathe will be distributed using PyPi and installed using pip.

create a PyPi page for hosting the release packages.

Threading Operation:

• G76 Threading Cycle

Provide examples on how to use the library from a python app

The CodCov banner in the readme me file, when clicked return a 404 website error

Provide a FreeCAD plugin to aid testing of the library

LLPoint has been added.

This is to add shell unit tests for the others.

Define what the minimum viable product looks like to release. Once released a standard release cycle will be followed.

This should be handled by a post processor

Test suite and automated testing required for PRs

as title

compete the community profile to encourage and aid contribution

Add to current imagedraw functionality

1. Plotting only rapid (G0)
2. Plotting only cutting moves (G1, 2 and 3)
3. Handle other than lines (G2/G3)

The part outline is added to the finishing paths by default if finishing is set to true.

This is no good for facing or parting operations.

Bug in the boundbox method in LLSegmentGroup

roughing passes should merge in to the next profile pass to ensure consistent tool engagement on the profile pass.

Create an overview document to give a pictoral example of the internal class stucture and what each class represents.

This should help with integration and on-boarding so it should be basic / simple to understand.

Support use if left hand cutting tools.

Cutting direction left to right.

Name the examples with the type of operation. i.e Profile, Face

I'm trying to load your lib on my debian testing machine with FreeCad 0.18.4. I copied the whole folder in my mod directory then i type in the python console:

import LibLathe

without errors, but i cannot find it anywhere. Thanks
