Been shopping a small part to be machined in Delrin. It measures about 1x.75x.25 -- fairly smooth geometry and described to us by a 5 axis shop as an easy part. The 3 axis shops say doable but need fixtures and indexer. There is a wide range in pricing for each part between shops and also a wide range in "programming" time pricing between shops. We are new to jobbing out machined plastic parts and are unfamiliar with your practices. Would anyone be so kind as to elaborate on why the discrepancies?
Is it not the case that the surf and mastercam programs or the like turnkey most of the programming set up time or is it as manually time consuming as we have been led to believe? Is programming time an area for negotiation and are these shops just testing our ability to sniff out a margin enhancer? We're getting from 2 hours to head scratching on programming times...
Thank you for your time in advance and look forward to your responses.
