Case Study
·Commercial Kitchen Manufacturing·2026

The post processor
was locked.
So we built
a layer on top of it.

A commercial kitchen manufacturer was manually editing CNC code before every machine run. The post processor was locked. The problem wasn't going away on its own. Kaisyn built a deterministic analysis framework that sits between the machine output and the operator; interpreting, validating, and flagging, so the operator knows exactly what to look at and why.

Holz-Her Eco Master 7120 nested CNC router. Locked post processor. Every job required manual code edits before the machine would run.
The Situation

Manual edits.
Every single job.
No end in sight.

The shop runs a Holz-Her Eco Master 7120 nested CNC router for commercial kitchen fabrication. Precision work. High repeatability requirements. The kind of environment where a missed edit doesn't just slow you down. It can ruin a part.

The problem: the Holz-Her post processor is locked. It generates HOP files, but those files require manual edits before execution. Lead-in geometry, tooling validation, depth strategies. All of it was operator judgment, every time. Some operators knew what to look for. Others didn't. The process wasn't documented. The rules lived in people's heads.

As volume scaled, the risk scaled with it. That's when they called Kaisyn.

The Problem

Three constraints.
One locked system.

01
Locked post processor
The Holz-Her post processor can't be modified. It outputs HOP files in a fixed format. Any issue with that output has to be caught and corrected downstream, by a human, before the machine runs.
02
Operator-dependent judgment
Lead-in selection, tooling validation, depth strategy review. All of it required an experienced operator to read the code and make judgment calls. That knowledge wasn't written down anywhere.
03
No scalable system
The manual edit process worked when volume was low. As job count increased, the risk of a missed correction increased with it. The process couldn't scale without something deterministic replacing it.
The constraint wasn't the machine. It was the gap between what the machine output and what the operator needed to know.
Fix that gap, and the machine runs reliably. Every time.
The Solution

A post-post processing
analysis framework.

Not a post processor replacement. Not a workaround. A deterministic analysis layer that reads the HOP file output, interprets what the machine is about to do, validates it against documented shop standards, and tells the operator exactly what requires attention and why.

Week 1
Audit
CNC workflow audit and HOP file analysis. Every machining operation mapped. Every condition requiring manual intervention identified. Nothing assumed.
Week 2
Classify
Operation classification and rule documentation. Every machining rule written down. Lead-in logic, tooling validation criteria, depth strategies. Formalized for the first time.
Week 3
Build
CAM analysis engine development. The framework that reads HOP files, applies the rule set, and produces operator-readable output with flags and recommendations.
Week 4
Transfer
Operator validation and documentation handoff. The system tested against real jobs. Documentation written. Knowledge transferred. The shop owns it.
What the Framework Does
Reads HOP files generated by the locked Holz-Her post processor
Identifies every machining operation: pockets, contours, drilling cycles
Interprets tool selection and validates against shop standards
Evaluates lead-in geometry and depth strategies
Detects conditions that require manual intervention
Produces operator-readable analysis with clear flags and explanations
Documents machining rules for future automation expansion
The Analysis Output
CAM post-processing analysis output
Operator-readable analysis output. Every operation classified. Every flag explained.

The Handoff

The rules are written
down now. For good.

Every machining rule that used to live in an operator's head is now documented. Lead-in logic. Tooling validation criteria. Depth strategies. Conditions that require manual review. All of it captured, structured, and written in language an operator can actually use.

The user guide was written, reviewed with the operators who run the machine, and delivered as a structured reference document. Not a manual no one reads. A working reference built for the actual workflow.

Machining rule reference — all operations documented
Operator validation workflow — step by step
Condition library — when to intervene and how
Future automation roadmap — rules ready for the next phase
Operator Training

Built it. Documented it.
Then taught it.

The documentation tells you what to do. The training shows you how. Operators received a full walkthrough of the framework; how to read the analysis output, how to interpret the flags, and how to make the right call when the system surfaces a condition that needs attention.

This is the full loop. Not just a system delivered. A system understood.

The Outcome

Manual edits, down.
Operator confidence, up.
Rules on paper, permanently.

The shop went from manual CNC code edits on every job to a structured validation process where the framework does the analysis and the operator reviews the flags. The target was 90% reduction in manual edits. The system is designed to get there systematically, not optimistically.

More importantly, the machining rules that used to exist only in experienced operators' heads are now documented, validated, and owned by the organization. When someone new joins the floor, the knowledge transfers. When volume increases, the process doesn't break.

And when they're ready to automate further, the rule documentation is already built. The next phase doesn't start from scratch.

Work With Us

Have a process that
needs to be stabilized?

We audit the workflow. We find the friction. We build the system that replaces judgment with rules, and rules with documentation. Then we hand it off running.
