In precision machining, it is desirable to measure the workpiece form profiles to provide feedback for control to maintain machining quality. A water beam assisted form error in-process optical measurement approach has been proposed to solve the opaque coolant problem to permit form error in-process optical measurement. To have more comprehensive understanding of the method, factorial and preliminary parameter tests were conducted. It was found that the water flow rate Q_w and the height of medium h_m are the two most important parameters affecting the transparent window size A_t. For Q_w, there is a transition of flow state changing from laminar to turbulent. Increasing h_m generally gives smaller A_t. The preliminary parameter test results also show that the conditions Q_w∈ [0.6-0.75ml/s] and h_m ∈ [0.3-0.4 mm] give better stability for A_t.
