circular interpolation commands for cnc machining

circular interpolation commands
G02 interpolation clockwise, counterclockwise for interpolation of G03, the format in the XY plane, as follows: G02/G03X_Y_I_K_F_ or G02/G 03 X_Y_R_F_, where X, Y is a circular arc end coordinates, I, J as the starting point to the center of the circle arc in X, Y axis incremental value, R radius, F is the amount of feed.
Note that in the circular arc cutting, q is less than or equal to 180 DEG R positive; q>180 degrees, R negative; I, K R can be specified specified, when both are specified at the same time, the R instruction is preferred, I, K is invalid; R can't do the whole round of cutting, the whole round cutting can only use I, J, K programming, because through the same point, the same radius circle there are numerous, as shown in figure 2.
Fig. 2 through the same point circle
When I and K is zero, it can be omitted; both G90 and G91 mode, I, J, K according to the relative coordinate programming; circular interpolation, not with the cutter compensation instruction G41/G42.

Hot product: Solar panels weather challenges

olar panels have barely budged from their place within the upper ranks of the top 10 products on the Global Sources website in the past 12 months despite "dark" times.

Month-on-month buyer inquiries dipped in July 2012, although aggregate searches in the first six months of 2012 are 42 percent higher YoY.

In recent months, solar panel business in the EU has narrowed after some member countries reduced feed-in tariffs for large PV installations. The EU is the line’s largest market, accounting for about 75 percent of the world’s total installed capacity.
