Can I use a circular saw for precise cabinet making
If you're making many similar cuts, it's often worth it to build a jig. Jigs will allow you to make many repeatable cuts, quickly and easily.

There are also loads of guides, slides, and jigs available off the shelf (or online anyway).

Also, don't forget to use the proper blade.  You probably wouldn't want to make furniture with a 24 tooth blade, unless you don't care much about the cut quality. If you're cutting plywood or veneers, you'll want to use at least an 60 tooth blade.
