Chris Wilson Posted April 30, 2010 Share Posted April 30, 2010 My maths is appalling, I am sorry to say. Yesterday I wanted to work out the X and Y axis movement on a milling machine to drill two holes opposite one another skewed 45 degrees from the vertical at a known PCD . I had the machine zeroed on the centre of the hole around which these drillings were needed. Took me ages as I have forgotten most of my Trig and I couldn't find a suitable calculator Is there any easy to use engineering software for this sort of thing? It's at times like this a CNC machine seems wonderful Ta! Quote Link to comment Share on other sites More sharing options...
dandan Posted April 30, 2010 Share Posted April 30, 2010 There's a real simple online trig calculator here http://www.visualtrig.com/ Not sure if the Desktop version is any good... Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted April 30, 2010 Author Share Posted April 30, 2010 Thanks everyone, I had forgotten the extra info in the Zeus book, and I have a copy somewhere! Cheers, some great info. Quote Link to comment Share on other sites More sharing options...
