With the increased power of the TB-DECO and at the request of our customers, the deburring process has undergone modification. Since the launch of the TB-DECO 5.01, the G913 macro can effect deburring of the dropped part in two ways:

  • In the conventional way, by mere hobbing of the cutting tool in X (standard case used to date).
  • Or by interpolating axes Z and X (turning), so as to obtain a chamfer, the angular length and value of which can be parameterized.
This second option is of great interest, for example, when using a cutting tool with a straight insert.

The reason is as follows: standard deburring of the dropped part by hobbing (see above) eliminates any burrs at the end of the bar but could lead to creation of another burr (Fig. 1).

This second burr is brought about because there is no angle on the cutting chisel. When using the second option (interpolating X Z), no burrs will be found at the end of the dropped part. You can now be assured that when the device returns to load the new bar, this will not be jeopardised by burring.

Only parameter P3 is compulsory. Parameters P4 and P5 can be omitted. In such cases, the default values will be taken into account.

Programming:
3 parameters can be programmed following G913 to define the legth and angle of chamfer to be executed.

P3 = length of chamber
P4 = value of chamber (default = 30º)
P5 = feed during chamfering (default = #3002)
