Using the DNCI mode of Fanuc-0 for continuous machining of large programsWritten by ControlOn
Synopsis: For machining very large programs on a general purpose CNC, internal part program memory may become a constraint. This is usually case with CAD generated programs for Die milling where program size may run into range of 20-30Mb, which is far beyond capacity of a standard Fanuc-0 control. To execute such programs alternatives are:a) Breakup programs to smaller manageable chunks as per memory capacity of control and execute it one by one. b) Use DNCI function available with control. Option a) is cumbersome since a lot of pre-processing has to be done to break up program and while machining, after execution of every chunk part program memory must be cleared, a new chunk loaded and executed. This involves a lot of operator intervention and may result in serious accident if a chunk out of sequence is loaded. This is where DNCI option can be a big advantage.
| | Laptop Computer Extras for the Mobile TravelerWritten by John San Filippo
A laptop computer certainly provides you with an unprecedented level of freedom and mobility away from office. However there are a few extras you might want to bring along on your laptop travels:Extra 1: portable printer If you travel a lot, you never know when you might need to commit one of your digital documents to paper. Sure, you can probably find a Kinko's, or even business center at your hotel, but experienced business traveler knows you're much better off when you're not at someone else's mercy. Extra 2: USB hub If you need to connect to several external devices simultaneously, one or two USB ports on your laptop may or may not be sufficient. If not, keep an inexpensive four- port USB hub in your laptop case. Extra 3: PC card token ring adapter
