i HAVE A DELL LAPTOP WITH i7 PROCESSOR 16GB RAM NVIDA M1000 VIDEO, RUNNING MASTERCAM 2017 The problem I see is when I do a file save it takes about 20 seconds to save file , This is NOT a large file at all. But If I turn on auto save after every operation in my config the machine saves right not now NO time lost waiting to save ... But really dont want to have auto save on ... So can someone please explain why this is ? All I can come up with is maybe auto save only adds the next operation to the existing file but dont over write the complete file ... { just my thoughts } I was told its do to having a spinner drive vs SSD drive , thought it made sense till I saw how well auto save worked ... Thanks in advance ...

Hi guys, Here's what we need. a 6-32 tapped hole thru cast 1/4" thick. Thread minor has to be .109 to .112. Hole is made with .125 carbide drill. The roll tap give a nice minor dia, but were eating thru the taps like no tomorrow. The operator has been going thru about 8 taps a shift. Originally the program had the tap rpm set to 1000 with a feed of 37.5. I thought that was way too fast. the first couple flutes on the tap would get burned up in no time. So i slowed the S&F down. But I dont think I slowed it down enough. Currently its set at S750 F23.4375. I was reading thru some of these forums and many people said that the max rpm for small dia tapping was around 200-250 rpm. If I need to slow the tap down to prolong its life, then I guess thats what i have to do. Only thing that will affect is longer cycle times. What are your thoughts on this issue? Could I start with a smaller hole and use a plug tap? Is it the coolant? What variables am i missing? Thanks, Matt
