The CEPC is a proposed circular electron positron collider to study the Higgs boson more accurately. To make sure the machine works well, the compatibility of the machine and the detector is very important. In order to make sure the detector is compatible with the machine, two kinds of problems must be resolved. Firstly, the mutual influence between the machine and the detector must be well studied. It includes the beam induced background, the influence on the beam status from the detector

Secondly, the interface between the machine and the detector must be well designed, including the mechanical supporting, the procedure to assemble the interaction region and so on. In this talk, we present the recent progress of the IR design and MDI study of CEPC. The dominant sources of beam induced background have been studied and some preliminary results are obtained. The compensating solenoid and anti-solenoid will be used to suppress the influence on the beam status from the detector solenoid. A global design of the interaction region is undergoing to balance the conflict of performance between the machine and the detector.
