Program entry In HEIDENHAIN conversational and DIN/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.
(TCPM = T ool C enter P oint M anagement)
3-D machining (software
option 2)
2 Keeping the tool normal to the contour
2 Tool radius compensation perpendicular to traversing and tool direction
Rotary table machining
(software option 1) 1 Programming of cylindrical contours as if in two axes
1 Feed rate in distance per minute
