post.
OPERATION◆
●Full-screen editing interface and foreground-background processing operation, which
can do programming, parameter adjustment etc at the same time
●2D/3D graphic preview or simulating operation before machining, coordinates display,
free shifting between 2D/3D graphic; graphic can be scale up/scale down, translate and
rotate freely.
●Multilevel password protection, such as program, parameter protection to convenient
equipment management
●Start machining at random block or tool number
●Compatible with popular international CNC system in instruction code and most program
can be run directly without amendment
