I have not seen any type of this being done. You can increment the A axis and do a parrallel cut along the X axis for a finish routine. But, I want to see a HSM stragety that revolves the model on tha A axis and moves the cutter along the X and Z axis for a HSM 4th axis stragety while maintaning a constant cutter load. This should keep your eye on the ball for a while. How about taking on a 4th axis adaptive clearing strategy. I have not seen any type of this being done.

Of course EPCs should be public. Apart from anything else they'd be useful to other potential purchasers (like the rest of the info on the house). And the 3-month validity should probably be upped too. That's often not long enough for a sale to happen and the chances of is becoming invalid over that period are low. I hope you get somewhere with this. Peer pressue is probably the most effective way of getting 'most people' to improve the generally woeful houses and habits in this country. Well done Julian.

Made to go to expo in the rain. I did at least use debconf to improve the tunnelx java packaging. Take some mild consolation from the fact that it's gone rather soggy in the UK too (after months of drought). Poor Julian. Made to go to expo in the rain.

]]> Comment on Encoding 2D angles without trigonometry by Nick http://www.freesteel.co.uk/wpblog/2009/06/encoding-2d-angles-without-trigonometry/comment-page-1/#comment-50039 Nick Sat, 17 Jul 2010 10:39:01 +0000 http://www.freesteel.co.uk/wpblog/?p=1127#comment-50039 (This comment is directed more towards visitors than the author, this is how I wrapped my head around this concept) I discovered your site a few years ago and recently returned because of this post which I found interesting. I wanted to try and wrap my head around it, and a recent grad class helped. Once I understood that it is simply re-defining angles using the L1 unit circle (a diamond) as opposed to the standard L2 unit circle (a circle) it became easy to understand, and the rest is just algebra. What DID throw me off is the range of your angle: a = [0,4). As you know, the 'radian' angular measurement is defined by the distance traveled along the circumference of the unit circle in L2 space. If you follow the same definition in L1 space, the distance traveled around the unit circle is 8, thus should be: a = [0,8). When I did the algebra to convert the angle 'a' into a (x,y) point and saw that 'a/2' keeps showing up, it makes sense to just halve the angle straight off. Either way preserves the L1-norm: |x|+|y|=1. (For those interested, general Lp-norm is ||x||p=(|x1|^p+|x2|^p+...+|xn|^p)^(1/p), think c=(a^2+b^2)^0.5 ). This should be taught at EVERY engineering college, a 25%-300% speed increase is no laughing matter when your calling the function several million times.
