Scionwood for dormant grafting is best when the trees have gone dormant and before they wake up for the spring, i.e. January, February, in most climates. Some really cold climates have a huge window for cutting scionwood.
Then you would probably do your grafting in March or April, depending on your climate.
For summer bud grafting, as James says, you cut the buds off of new growth, keep watered and chilled, and quickly bud graft those onto the new tree when the bark is slipping, ie summer in most climates.
