Notation ： Swan published a accessory tool （ SGD ） on a near day——visualized NC code debugging tool (SGD)

SWANSC G-code debug tool (for short SGD) is a simple and effective built-in tool which can call simulation NC code intuitionisticly, simplely and rapidly. SGD help you call G code rapidly and correctly and check format of each command intuitionisticly. With SGD ， you can even check every G code and check every corresponding locus in the condition of a visualized three-dimensional graphics. SGD support kernel code of many NC systems such as FANUC 、 SIEMENS 、 HUAZHONG NC 、 MITSUBISHI.
