JB came in from Maui Wednesday morning. We went to a ShopBot training class on Friday and Saturday. ShopBot is a company in Durham that makes 'personal' CNC machines. Their CNCs are inexpensive, some less than $10K compared to other CNCs costing >$100K-500K. ShopBot CNCs are for wood and not metal but they are amazing machines.
A PC or laptop is used to run the ShopBot. Click the picture to see the album of pictures with some of the neat things that they can do. The tool that cuts the wood is a 3HP router or a spindle turning a 1/4 to 1/2 inch shanked bit and cuts 600 inches/per minute. That means it can cut a dado from end to end of a 8 foot sheet of plywood in less than 10 seconds. They can move the same length in 3 seconds. The video does not do the speed justice. We were cutting at 3 inches a second (poky).
