  Weyl semimetal (WSM) is an exotic topological state in condensed matter
physics. In this paper, based on a two-band cubic lattice model, we studied
WSMs with a pair of tunable Weyl nodes. It is pointed out that there exist
three types of WSMs with different tilt strengths: type-I WSM, type-II WSM and
type-1.5 WSM. In particular, type-1.5 WSM has one type-I node and one type-II
node. We studied chiral modes, surface Fermi arcs and quantum anomalous Hall
effect in different types of WSMs. In addition, we give an experimental setup
to realize the different types of WSMs based on timely technique.
