| Z-Plane Concentrical Roughing |
| ESPRIT Mold has powerful and easy-to-use roughing functionality which includes
an extensive set of high-speed cutting features such as: rounding of sharp angles and fluent step over
with cordial feed to avoid straight paths, allowing climb milling in all situations. Most importantly
the toolpath is optimized based on the results of the previous machining cycle(s),
(the dynamic in-process stock model), eliminating any “air cutting” and minimizing retract movements.
You can choose to calculate toolpath from outside to inside (collapse) or vice versa (expand).
A wide range of approach/retract positions complete this module, which is one of the most
outstanding features of ESPRIT Mold. |
| Roughing Re-Machining |
| The rest roughing capability of ESPRIT Mold enable the re-machining of
previously cut areas of the model resulting in a constant volume (stock) of remaining material.
During the rest machining a uniform volume of material is removed producing a constant cutter load
which optimizes your ability to perform high-speed cutting. The optimized re-machining of ESPRIT
Mold is achieved by always monitoring the in-process stock model to know where the remaining
material is at all times, even when machining undercut areas or utilizing inclined
(4 & 5 axes) cutting. |
| Z-Level Finishing |
| High-speed Z-Level finishing cycles available in ESPRIT Mold generate passes
of variable height in support of a constant scallop height producing a high-quality finish on your
work piece. This machining strategy is optimized by levels and by zones with smooth circular
approach movement and fluent stepovers. The Z-Level zigzag strategy offers faster cycle time
and the best quality along vertical walls. This finishing cycle optimizes the tool path by
rounding internal sharp edges for high-speed cutting (HSC) and providing G-Code output
utilizing G2/G3 circular interpolation whenever possible. |
| Rest Material Machining |
| ESPRIT Mold’s ‘on air’ technology for approaches and links of the toolpath
is applied to optimize the cycle times for rest material machining. Vertical edges are machined
by Z-plane tool motion and the planar edges by constant 3D step concentric paths. The calculation
of bi-tangency limit curves is optimized to produce fluent and continuous toolpath. On horizontal
edges, the Clean strategy generates progressive and constant removal of the rest material. |
| Planar Zone Re-Machining |
| Combined with the Z-plane contouring, the planar zone re-machining produces
excellent results even on the most complex parts. Zigzag or concentric toolpaths are available
and the clearance distance from walls is independently controlled and may be different than
clearance used with respect to the stock. |
| Concentrical Milling with a Constant Stepover |
| In this finishing strategy ESPRIT Mold produces toolpath inside a closed
curve, avoiding any number of islands. With this cycle’s constant 3D stepover ESPRIT Mold
produces uniform milling of multiple complex surfaces with a single machining operation.
Sharp angles within the toolpath are rounded, and the stepovers are fluid to allow
high-speed cutting. |
| Combined Strategies |
| Combine several ESPRIT Mold machining strategies to optimize the machining
techniques applied to the work piece, reduce cycle time, improve part quality and minimize
tool wear. For example, radial or spiral finishing strategies combined with constant
3D step concentric milling provides higher machining speed, superior surface quality,
longer tool life and optimization of cutting parameters. |
| Milling Between Two Curves |
| Use ESPRIT Mold’s Two Curve machining strategy to clean mold areas with
fluid toolpath motion, even for concave or convex edges. Simply select two curves on the mold
and the material between those two curves is removed while respecting any stock allowance
and the work piece surface(s). The initial stepover is calculated from the maximum distance
between these two selected curves. Should the curves have a very different shape, a
simple interactive graphic tool is provided to allow nodes on the curves
to be synchronized. |
