I just went through and depicted all of the refs and correlated them with the correct bibliographic entries, however this ref I couldn't correlate. If someone else knows what it is supposed to be I would appreciate their help. Thanks! [[User:Wizard191|Wizard191]] ([[User talk:Wizard191|talk]]) 17:52, 9 March 2010 (UTC)
Sorry, I frankly do not inderstand what topics are being didcussed here.NC as an adjective? This is an exactly defined technical term, to me you're splitting hairs and avoiding questioning CNC versus DNC technology; meaning, to me, running programs on a machine from a separately connected computer which hosts editing software and sends only G/MS/T information,typically in a serial port connection. Related, there is no mention of how most CNC machinery typically includes machine-specific SOFTWARE ROUTINES AS NECESSARY TO DEAL WITH, FOR EXAMPLE, tool changes, tool offsets,and the 'BACKLASH' mentioned. Sorry for the inadvertant capslock.. One major issue not mentioned is the use of box ways versus linear guides. Machinists and shop owners appear to have attitudes, preconceptions, and ego involved, and it's a favorite subject for some salespeople to bring up. The backlash assumption applies to machines using traditional acme-threaded leadscrews, something which may may not apply to newer ballscrew machines. And there's no discussion of how, particularyin cnc lathes, manufacturers also supply options for non 'cut time' operations such as feeding or measuring operations. These can very significantly affect throughput and geometric accuracy. Then, the final missing issue is probing. And a quite seriously presumputous note about x86 basedindustrial computers; The sl20 shown has a 16/32 bit motorola processor, zero wait state memory and a history of damage not from electromagnetic fields, but fork trucks and lightning <ref></ref>touching connected RS 232 wires. I'm not trying to be negative here but to provide critical reasoning, sorry my tone comes over this way.
