Hello ppl.
I need to come up with a device which is capable of tracing shapes from drawings (two dimesions only)into a PLC. This will act as data for a material dressing machine. The accuracy reuired is not high (say 0.5 mm).
I believe I can control the machine well if I can resolve the shapes into a set of orthogonal coordinates pairs. However the only solution I can think of yet, to trace the shapes, is to use a tracing head made up of four photoelectric sensors (the shapes can be drawn in thick lines say 3 mm). The head would follow the shape outline driven by two motors with encoders.
My client is not keen on using a PC and scanner which would be much more reliable and perhaps even cheaper.
Could anyone suggest other economical solutions?
Regards
