Dimensions Drawings for the Laser

Dimensions Drawings for the Laser

(OP)
Now that it is possible to transfer information digitally from a CAD package directly to a laser for cutting parts from sheet metal or plate, how many of you still completely dimension the drawings?  If you don't completely dimension the drawings, what sort of dimensions, if any, do you show on the drawings?

RE: Dimensions Drawings for the Laser

At minimum I would throw a couple dimensions on there for checking to ensure the offsets are set correctly (something that can be measured easily on the shop floor).  Overall dimensions should be included for quoting purposes.

If the cad data is available I see no reason to create a cluttered drawing.  Include the information needed to inspect the part to the level you need to be satisfied the part is good.

RE: Dimensions Drawings for the Laser

Sounds like you are asking two separate questions.

>  Presumably, most laser cutting systems will have a pre-processor that would take CAD data and format it accordingly for a cutting process, including corner and kerf corrections.  

>  Dimensioned drawings are specifically for human consumption, so while one might transfer a CAD database for fabrication, a dimensioned drawing would be required for human inspection and verification that the part meets its intended requirements, which might be quite distinct from the fabrication data.
