TOL S.A.

Angle cutting quality

Loops

The Loop function is used to add a complementary path which is used to get the best cutting quality of the angle in that point : the path quits the contour in continuation with the previous contour element and it is placed in continuation with the next contour element.
TOLfab automatically adds loops with a radius defined by the user. Loops are added whenever the angle is less than the value defined by the user.

Straight lines loop

Straight lines + arc loop

Tangential arc loop

Stop on small angle

The Stop on small angles function is used to assign a Stop (G09 in ISO) code on the angles smaller than the filled value. This code makes the NC speed be annuled on this angle and restart immediately.

Gradient of speed

Another way to ensure quality is to slow the speed progressively, in case of sharp angles or of very small radiuses.
The user defines the number of stages of lowering speed, the percent of diminution of speed at each stage and the length of each stage.
