CNC Milling Tool material representation

阅读更多关于 CNC Milling Tool material representation

问题 I'm writting CNC simulator for 3-axis milling tool. At first attempt I have represented the material as WxHxD box (W - width, H- height, D - depth) with W and D divisor parameters. So for example W = D = 120, H = 50, W-div = 20, D-div = 20: At each step the mill is removing material and H coordinate at each division point is adjusted simulating material removal: This method is OK for started. But to simulate full precision of milling tool the divisors should have hight values, i.e. for

I want to parse an SVG file using python to extract coordinates/paths (I believe this is listed under the "path" ID, specifically the d="..."/>). This data will eventually be used to drive a 2 axis CNC. I've searched on SO and Google for libraries that can return the string of such paths so I can further parse it, but to no avail. Does such a library exist? Ignoring transforms, you can extract the path strings from an SVG like so: from xml.dom import minidom doc = minidom.parse(svg_file) # parseString also exists path_strings = [path.getAttribute('d') for path in doc.getElementsByTagName('path
