yes, tuanny
15 amp service is carried on a 14/3 or thicker (probably 12/3 {lower number is heavier})
you will need probably a 50 or 60 amp service,
this can be provided by running 2 or 3 12/3 wires. fed by 30 amp breakers, but, perfect world, a 50 or 60 amp subpanel (a small circuit breaker panel in the garage, with a 50 or 60 amp breaker, with 20 amp breakers for each machine coming out of tbe panel
an electrician will need to run a piece of 8/3 wire from house to garage (or, as i said, 2 or 3 additional 12/3. drops)
not a good idea to cheat on this and starve equipment for power when it runs, lights will dim & you will beat the hell out of your expensive electronics
you don't want to overheat the wire feeding the garage (fire danger) and you certainly don't want to join the group who blow a system board during a storm and take a $2000 hit and suffer downtime
i am not trying to scare you, but give you good advice to save you money in the long run
(search signs101 for main board or system board to see how frequent this type of problem is
