About GTC

On this site you find information that will support you in the implementation of the GTC Format. The GTC Format is a complement to ISO 13399 and therefore has been created in close connection to it. The need for GTC comes from the fact that ISO 13399 does not cover all the information that is needed for an efficient exchange between the cutting tool vendor data and the application. Since there cannot be any contradiction between ISO 13399 and GTC, we expect, going forward, to see more GTC elements becoming part of ISO 13399. GTC defines the structure and content of the digital cutting tool catalog which is contained in the  GTC package. If you are a tool vendor, your challenge is to provide your digital product catalog as a GTC package. If you are an application developer of a receiving system, your goal is to unpack the GTC package and extract the cutting tool data you need.
