I am a 10+ mastercam user. I started a company about a year ago and switched to Catia due to meeting our customers needs. Now I have an order for 2 pretty complex impellers and I am going back to mastercam. I have started to play around with the demo software. We are about to purchase Mastercam X7 with multiaxis but not blade expert due to the fact it is an additional ***** So I have a couple things I was wondering . Any suggestions for starting out? Is there any good tutorials out there. How good is Mastercams support with stuff like this? Im also open to paying for help from a programmer that has experience in machining impellers.
