Fusion Multi-Channel Post Processor
Multi-channel machines run two or more programs at once: two turrets cutting together, a main and sub-spindle working in parallel, or a Swiss-type with gang and back tools. We build Fusion posts that output separate channel programs with correct wait codes and synchronisation.
Parallel cutting, synchronised safely
On a multi-channel machine, each channel (also called a path or system) has its own program. Channels run at the same time and meet at wait points so that, for example, the upper turret does not start until the lower turret has finished a cut, or both spindles are ready for part transfer. Wait code syntax differs by control: FANUC uses M-code waits with P values, Siemens uses WAITM, and other controls have their own methods.
ENGIMANDI builds Fusion multi-channel posts. We assign operations to channels, output separate programs in the format your control expects, insert matching wait codes at synchronisation points, support balanced (pinch) turning where two tools cut together, and coordinate part transfer between spindles. We work with Fusion's multi-channel machine and simulation capabilities where available, and review timing with your team.

Multi-channel questions
What is a channel?
A channel (or path) is an independent program stream. Multi-channel machines run several at once.
Why do wait codes matter?
They keep channels in step. Missing or mismatched waits can cause collisions or stalls.
Can Fusion program multi-channel machines?
Fusion supports multi-channel machining for suitable machines. We build or adapt the post to match your machine.
Is pinch turning supported?
Yes, where your machine supports it and the programs are set up for it.
What about single-channel sub-spindle lathes?
