摘要： A tool holder having force sensors includes a first connection portion, a second connection portion, a first sensing portion, a second sensing portion, at least one first force sensor and at least one second force sensor. The first connection portion connects a cutting tool along an axis. The second connection portion connects a spindle along the axis. The first sensing portion having at least one first hole connects the first connection portion along the axis. The second sensing portion having at least one second hole connects the second connection portion and the first sensing portion. The first force sensor disposed in the first hole is to sense a torsional force. The second force sensor disposed in the second hole is to sense a bending force. The first sensing portion has a bending stiffness greater than that of the second sensing portion.
