I've had to produce some soft urethane parts to pretty tight tolerances and we always used grinding operations to finish the moulded parts. Used it on parts down to about 35 Shore A. Not sure how it would do on anything softer.

sometimes you can freeze them and get a quick cut. pack them in dry ice (CO2) until they are cold soaked and then quickly clamp and cut. If it is something simple like a single slot on a mill, or an outside diameter on a lathe, then this is said (by a trusted co-worker) to work fairly well.

of course once it warms up .... so you have to work fast.
