Fusion Post Processor Optimisation for Faster Cycle Times

Your post may be safe but slow. We optimise Fusion posts to remove wasted motion and time: smarter tool changes and retracts, rapid handling, high-speed machining modes, efficient cycles and compact code, all without compromising safety.

Seconds per tool, hours per month

Generic posts are written to be safe on every machine, which often means full retracts to home before every tool change, repeated modal codes, conservative rapid handling and cycles expanded into long blocks of linear moves. On a single part, the extra time seems small. Across hundreds of tool changes and thousands of parts, it adds up to hours of lost spindle time.

ENGIMANDI analyses your posted programs and machine behaviour, then optimises the post: retracts only as far as safely needed, tool preselection, spindle and coolant overlapped with moves where the machine allows, high-speed and look-ahead modes switched on for finishing, native canned cycles instead of expanded moves, and removal of redundant output. We measure cycle time before and after so the benefit is clear.

Capabilities

Where optimisation saves time

Proven areas for faster Fusion programs.

Tool Changes

Preselection and overlapped moves to shorten chip-to-chip time.

Retracts

Clearance moves instead of full home returns where it is safe.

HSM Modes

Controller smoothing and look-ahead modes set per operation type.

Canned Cycles

Native cycles output instead of expanded linear moves.

Compact Code

Redundant codes removed, arcs output where possible and file size reduced.

Measured Results

Cycle times compared on real programs before and after.

Use cases

Typical projects

  • Chip-to-chip time reduced on a production VMC
  • High-speed mode switched per roughing and finishing
  • Drilling output changed from expanded moves to cycles
  • Large 3D programs reduced in size for machine memory
  • Lathe index positions optimised for short tool changes
  • Retracts limited by fixture height on an HMC

FAQ

Optimisation questions

How much time can post optimisation save?

It depends on the part and machine. Jobs with many tool changes or short operations often see noticeable savings.

Is optimisation risky?

Every change is reviewed for safety, and retract heights respect your fixtures and machine limits.

Will high-speed modes affect accuracy?

We set tolerances per operation type, balancing speed for roughing with accuracy for finishing.

Can you optimise for a specific controller?

Yes. Each controller has its own smoothing and cycle features, which we use correctly.

Do you also optimise toolpaths?

Our focus is the post, but we also advise on Fusion CAM settings that affect cycle time.
