Canned cycles (·M· model)<br />

The roughing operation defining parameters are:<br />

Fz Penetration feedrate.<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 milling is carried out 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.<br />

F Surface milling feedrate.<br />

S Spindle speed.<br />

T Roughing tool.<br />

If programmed T=0, there is no roughing.<br />

D Tool offset.<br />

Spindle turning direction (icon).<br />

Clockwise.<br />

Counterclockwise.<br />

Tool radius compensation (icon).<br />

Without compensation.<br />

Left-hand compensation.<br />

Right-hand compensation.<br />

Programming of M functions.<br />

Activating or deactivating the execution of M functions before machining. The cycle allows<br />

editing up to 4 M functions. To execute only some of them, define them first and leave the<br />

rest of the data unprogrammed.<br />

The editor will only show this option if the user has configured the editor to allow<br />

programming M functions.<br />

Finishing parameters:<br />

In order to carry out the finishing operation, the roughing must be defined with tool radius<br />

compensation. The operation removes the finishing stock (δ).<br />
