The ProtoTrak SMX CNC system from Tiverton-based XYZ Machine Tools Ltd is now available with an updated DXF file converter.
By importing CAD files in DXF or DWG formats (via a USB or a network connection), operators can quickly simplify the data by turning off layers such as borders and dimensions before choosing their initial datum point.
Once selected, the standard ProtoTrak conversational programming language is used to create the machining path.
The advantage of this capability is that all points are taken from the CAD file, so no dimensional mistakes can occur as a resultof the operator inputting incorrect data.
Once the program has been created, the operator can use the standard features of ProtoTrak to confirm the tool path or verify the part in 3-D to show the machining process on the control screen (

For companies using 3-D solid-modelling software, ProtoTrak can also import Parasolid data (.X_T format), which can be viewed in 3-D — along with the ability to zoom, rotate and ‘pan’ the drawing.
Furthermore, using ProtoTrak’s ‘Inquiry’ function, the operator can interrogate the Parasolid file to ensure that the correct tooling is used and that cycle times are minimised.
