Does angular acceleration on a spinning disk increase centrifugal force?

not immediately
alpha = ang acceleration = d omega/dt
F = m Ac = m v^2/R = m omega^2 R
where omega = angular velocity and v = tangential velocity (omega*R)
and m is any particle on the disk at radius R
v is velocity not acceleration
however over any finite time, acceleration changes velocity so only indirectly
