MillPlus IT (1 CPU)

MillPlus IT (2 CPUs)

Brief description

• Basic version: 3 axes plus spindle

• 6 additional axes plus 2nd spindle (option)

• Digital current and speed control

Programming

• ISO free or supported program entry

• IPP part programming

Position data

• Nominal/actual value and distance to go for line segments and arcs in Cartesian

coordinates, dimensions absolute, display and entry in mm or inches

Contour approach and departure

• Via straight line: tangential or perpendicular

• Via circular arc

• Via helices

Tool compensation

Tool radius in the working plane and tool length

Tool tables

Tool table with 255 tools

Tool management

The tool changer is controlled by the integrated PLC. The MillPlus assumes the

entire tool management including tool life monitoring, replacement tools and

oversized tools

Cutting data calculation

The MillPlus calculates the optimum values for feed rate and spindle speed for the

selected tool and workpiece material

Constant contouring speed

• With respect to the path of the tool center

• With respect to the path of the tool edge

5-axis machining

• Reduced feed rate during plunging

• 3-D tool compensation through surface normal vectors

• Jerk reduction

Geometry look-ahead

The MillPlus calculates the geometry ahead of time (150 blocks) to adjust the feed rate.

In this way it detects directional changes in time to accelerate or decelerate the

appropriate NC axes.

Tilting the working plane

The MillPlus features a special coordinate transformation for controlling swivel heads

and tilting tables. The MillPlus compensates the offsets of the tilting axes and tool

lengths.

3-D machining

• The offset of the tilting axes are compensated so that the tool point location remains

unchanged with respect to the contour

• 3-D tool compensation through surface normal vectors

Machining with rotary tables

• Programming of cylindrical contours as if in two axes

• Feed rate in mm/min

Milling/turning applications

• Turning cycles: roughing, boring and transverse/longitudinal recessing

• Programming a rotary axis like a spindle

• Constant cutting speed

• Programmable tool orientation

• Unbalance detection and control

Free contour programming

Contour programming with graphical support for workpieces that are not dimensioned

for NC (IPC)

Subprogramming

Program section repeats, subprograms, program calls

EASYoperate

Manual operation

• Setup and datum setting

• Simple entry and execution of cycles with actual-position capture

(teach-in/playback)

• Graphic support for cycle programming

Fixed cycles

• Drilling/centering, peck-drilling, reaming, back boring, conventional and rigid tapping,

boring, slot milling, rectangular and circular pockets, clearing level surfaces,

machining patterns

• Contour pocket (contour-parallel) with islands

• Measuring cycles

Parallel operation

Writing a program while another program is being executed with

graphical support

Coordinate transformation

• Datum shift, rotation, mirroring

• Scaling

Points

• Programming with points from the point memory (256)

Programming aids

• Graphical support during programming: ISO, ICP and IPP

• Further information through Info key

• Technology tables: (for recommended feed rate and spindle speed)

E parameters

 

• Mathematical functions: =, +, –, *, sin , cos , /

Programming with variables • Logical comparisons: (=, , <>, >, >=, <, <=)

• Parentheses

• tan , arc sin, arc cos, arc tan, an, en, In, log, absolute value of a number,

constant , negation, truncation of digits before or after the decimal point

Verification graphics

Display modes

Graphic simulation before a program run:

• Plan view

• Projection in 3 planes

• 3-D view

• Detail enlargement

Programming graphics

The contour of the entered NC blocks is drawn on screen while they are

being entered (2-D pencil-trace graphics)

Program run graphics

Graphic simulation synchronous to machining

Machining time

Display of the current machining time in the program run modes

Returning to the contour

• Mid-program startup in any block in the program and returning the tool to the

calculated nominal position to resume machining

• Program interruption, contour departure and reapproach

Datum table

Datum tables with 99 points including text

Pallet management

For simple management of pallets, workpieces and tool for automatic

machining of production jobs under control of the PLC
