Re: Getting Started BUilding a CNC Machine
James. This is a trade or hobby with a lot of moving parts. Reading about where to go or what to do with a new machine is daunting.
I see you refer to tolerances. What do you know about tolerances? You can or might learn to compensate with a tool path change or fudging a tool diameter, or maybe climb vs conventional cut to accomplish said tolerances.
Most consumer mills and lathes, Sherline, Taig, Grizlly, PM Matthews etc all build machines that will blow the accuracy of a 3D printer away. If you listen here or on sites similar, you will hear expectations from a 1000000.00 dollar machine from a 1500.00 dollar machine. It isnt going to happen. If you are looking at accuracy or tolerance of .001" or less, forget it. Then get out your feeler gauges, look at a .001' blade and tell me your part wouldnt fit. If it doesnt, your design is done incorrectly. Get started more than worry about aerospace quality.
A lazy man does it twice.
