CANNED CYCLES OF THE EDITOR<br />

CNC 8065<br />

(REF: 1209)<br />

·134·<br />

Pre-emptied circular pocket.<br />

4.14 Pre-emptied circular pocket.<br />

Geometric parameters:<br />

Xc, Yc Center of the pocket.<br />

R Pocket radius.<br />

r Pre-emptying radius.<br />

Z Part surface coordinate.<br />

Zs Safety plane coordinate.<br />

P Total depth.<br />

Roughing parameters:<br />

Canned cycles (·M· model)<br />

The roughing operation empties the pocket leaving the following finishing stocks. Both stocks<br />

are defined as finishing parameters.<br />

δ Finishing stock on the side walls.<br />

δz Finishing stock at the bottom of the pocket.<br />

The roughing operation defining parameters are:<br />

Δ Maximum milling pass or width.<br />

The cycle recalculates the pass so that all the passes are identical, with the same value as<br />

or smaller than the one programmed. If programmed with a 0 value, it assumes a value of 3/4<br />

of the diameter of the selected tool.<br />

I Penetration step.<br />

If programmed with a positive sign (I+), the cycle recalculates the step so all the<br />

penetrations are identical with the same value as or smaller than the one programmed.<br />

If programmed with a negative sign (I-), the pocket is machined with the given pass (step)<br />

except the last pass that machines the rest.<br />

In either case, the cycle limits the step to the cutting length assigned to the tool in the tool table.
