Talk:CNC Chop Saw

The majority of cuts are 2x's and most are probably repetitive so a good place to start for shorter material might be an extended table saw sled. A low tooth count framing blade could increase cutting speed and efficiency as well if switching the saw to a plywood blade is not necessary or too time-consuming.

For longer material the need to feed perpendicular to the blade makes the chop saw look simpler, but good even supports are generally needed underneath the whole length.

If a large Universal CNC gantry table has to be built either way a CNC table saw configuration might be more easily automated.

Speed obviously depends on the motions required by the user.

A chop saw will give the user more freedom to quickly change or verify individual cuts, but if the goal is to accurately know them all ahead of time a system where multiple pieces to be cut can be accurately and precisely clamped and/or guided together and fed to the saw will likely require fewer motions for users.

The user may also be able to assemble the next series of cuts while the saw operates.

So, can a brace and clamp structure near the saw blade can maintain square while roller supports allow for ease of motion sufficient that longer material could be cut on a table saw?

Without requiring significantly more space than the chop from above method?

Or more aptly how long of a board can be cut easily using a table saw sled method?

Which machine configuration requires more and larger expensive motors, bearings, table stock, and parts?

Also what configurations best fit with shop space layout and the likely need for rapid reconfiguration?

And portability of machines will be useful for future remote job site builds in which case large CNC tables are likely to be too bulky.
