Program entry
In HEIDENHAIN conversational and ISO
■ Nominal positions for lines and arcs in Cartesian coordinates or polar
coordinates
Position data
■ Incremental or absolute dimensions
■ Display and entry in mm or inches
■ Tool radius in the working plane and tool length
Tool compensation
■ Radius compensated contour look ahead for up to 99 blocks (M120)
2
Three-dimensional tool-radius compensation for subsequent changing
of tool data without having to recalculate the program
Tool tables
Multiple tool tables with any number of tools
Constant contour speed
■ With respect to the path of the tool center
■ With respect to the cutting edge
Parallel operation Creating a program with graphical support while another program is being
run
2
Motion control with minimum jerk
2 3-D tool compensation through surface normal vectors
2 Using the electronic handwheel to change the angle of the swivel head
during program run without affecting the position of the tool point.
