TSD XXY Automatic Alignment Platform TRX-A Calculation Formula

Characteristic:

When calculating the rotation angle, calculate the required displacement of each axis through the following formula to obtain the correct value.

Data calculation:

X1 axis: δ X1=R cos ( δθ + θ X1+ θ 0)-R cos ( θ X1+ θ 0)

X2 axis : δ X2=R cos ( δθ + θ X2+ θ 0)-R cos ( θ X2+ θ 0)

Y   axis : δ Y =R sin ( δθ + θ Y+ θ 0)-R sin ( θ Y+ θ 0)

δ X1 : Relative feed amount of X1 axis (mm)  ｝

δ X2 : Relative feed amount of X2 axis (mm)  ｝( Feed amount of ball screw )

δ Y   : Relative feed amount of Y axis (mm)     ｝

θ X1 : The angular position of the rotation center connected to the X1 axis ( ° )

θ X2 : The angular position of the rotation center connected to the X2 axis ( ° )

θ Y   : The angular position connected to the rotation center on the Y axis ( ° )

θ 0   : Calculate the workbench angle before action ( ° )

δθ: table rotation angle ( ° )

R : The radius distance from the center point of the platform to the center of the bearing connected to each axis
