However the CNC system still develops very slowly and the high-end system doesn’t have corresponding high performance, which is caused by three facts. The complex interaction between CNC system modules makes it difficult to improve its structure and function. Due to the low degree of open source, the available resources can’t be reached in the design and development process, making the whole project inefficient. Furthermore, it’s hard for a small team to make full use of all resources in the society to develop CNC systems, and this prevents making many function blocks such as
