Hello,
I have recently started using FreeCAD. I think it is a fine open source project !
I am designing some parts that would later be 3D-printed, and they have to match very well (it's a worm drive), so I was wondering whether there is a tool to check if the worm and the worm wheel match well. Apart from that, if the two models were developed in separate .FSCtd files, if is possible to combine them into one such file, so that I can check if they match well (hopefully that part can be automated).
Thanks in advance!
Is it possible to combine .FCStd files?

There is no real tool to check how well parts work together. This should be built into your design from the start. For example, if you have an 8 mm hole and an 8 mm pin, there is no clearance for one to fit into the other, so either the hole needs to be oversized or the pin undersized for manufacturing and real world assembly. Sometimes the holes are made the same size and one part is heated and the other cooled and assembled so when both reach the same temperature there is a tight friction fit, but that is another topic.

Until FreeCAD makes further progress with the Assembly branch you could try the following
1) Export your FreeCAD files to STEP
2) Use OnShape see https://www.onshape.com/ (You will need a browser that supports WebGL)
to combine the STEP files.

Before leaving FreeCAD for some other software I would encourage you to play around with hamish's Assembly 2 workbench for FreeCAD v0.15 addon.

In support of Cox's advice:
The said workbench has a tool to check whether parts do overlap/interfere
