Roughing it for 25 years : 

Roughing it for 25 years Or “was blind but now it sees!”

The way we were… : 

The way we were… 25 years ago by hand Sanding belt and rotatng wire brush Highly skilled

The first steps forward : 

The first steps forward Early auto roughing 1985 Excessive Touching up Less skill Cement by hand J.Robins Victoria

BUAR 1 : 

BUAR 1 Developed circa 1985 4 axis machine Head Left Right (x - rotary) Head up and down (z - rotary) Carrier in and out (y - rotary) Head tilt forward & back (Pitch) Fixed position - no spring “touch” BUAR 1

Cradle design 1985 – 2010!!! : 

Cradle design 1985 – 2010!!!

Dual brush head : 

Dual brush head One brush for each side of shoe Cross over at toe Poor toe roughing

Looking Hopeful : 

Looking Hopeful 5th Generation 1993 Limited touchup Significantly deskilled J.Robins Chippendale

BUAR5 and BUAC 1 : 

BUAR5 and BUAC 1 Rougher : 4 Axis Spring touch gives better control Cementer: 5 Axis X,Y,Z Actuator Pitch and Yaw Roll non servo Glue build up on brush

The Competition is on : 

The Competition is on Rough & cement one machine Roughing 5 axis Cementing 5 axis Programming more flexible Under engineered – inconsistent

Limitations of current Robots : 

Limitations of current Robots The comercial robots little change since 90’s Variations in natural materials Clamping inaccuracy & wear Edges picked up by brushes on more complex shoes

Vision of the future : 

Vision of the future New research Vision system Overcome variation Low resolution

True grit : 

True grit Grit blasting to replace roughing wheel

Conclusions : 

Conclusions Not there yet Current technology not really suitable for low wage producers Current technology not suitable for highly flexible systems Some promise in new approaches
