Tool library / 01
Focused tools for common quality-engineering work.
Each tool is built around a specific workflow rather than trying to become an oversized all-in-one statistical platform.
MV-QA-01 / PRIMARY TOOL
Process Capability Analysis Toolkit
Import measurement CSV data, set specification limits, and review Cp/Cpk with a trend chart, histogram, summary, and interpretation.

Working method / 02
From raw data to a reviewable output.
The tools are designed around the way measurement data actually moves through an engineering review.
STEP 01
Bring the data in
Import CSV data or paste values into an editable table.
STEP 02
Define the context
Select the characteristic, subgroup logic, units, and specification limits.
STEP 03
Review the signals
Inspect charts, summary statistics, assumptions, and obvious data issues.
STEP 04
Export the review
Save tables, charts, or a concise report for deeper analysis and discussion.
Design approach / 03
Useful before it is impressive.
Mechatrovich tools are shaped around clarity, visible assumptions, and quick internal review. They are not positioned as replacements for Minitab, JMP, or a company-approved statistical system.
See the engineering notesOne workflow per tool
Less navigation, fewer unrelated features, and a clearer first-use path.
Calculations need context
Capability numbers only make sense alongside stability, measurement-system, and sampling considerations.
Keep the data visible
Inputs, specs, rows, and calculated outputs remain easy to inspect and edit.
Export for discussion
The result should move into an engineering review, not remain trapped inside the tool.
Engineering reference / Siemens NX
A practical NX guide belongs beside the tools.

Is this measurement system acceptable?
Start with a clear answer, inspect the complete 20-measurement example, and see what must still be verified before approval.
Built for / 05
People who need a practical first review.
Formal analysis still belongs in the approved workflow. Mechatrovich helps make the data ready for that conversation.
Quality engineers
Quickly review capability, MSA, or SPC data before a formal report.
Manufacturing engineers
Investigate measurement and process signals without building a dashboard from zero.
Small suppliers
Create a clearer internal data review when full enterprise software is not always available.
Students & junior engineers
Connect formulas to the charts, assumptions, and workflow behind them.
FAQ / 06
Clear limits make better tools.
The tools support engineering review. They do not replace technical judgement, calibration, sampling plans, or company procedures.
Is Mechatrovich a replacement for Minitab or JMP?
No. The tools are designed for quick internal review, learning, data preparation, and communication before deeper statistical analysis in an approved system.
How do Mechatrovich tools help with engineering work?
They organize common review tasks—such as CSV preparation, capability checks, Gage R&R review, control charts, and report preparation—so engineers can reach a useful first result faster.
Can I use the result for a customer submission?
Use the output as a review aid. Validate the method, data, assumptions, and required format against your organization and customer requirements before submission.
Which tool should I start with?
Start with the Process Capability Analysis Toolkit when you already have measurement CSV data and need a structured Cp/Cpk review. Use the MSA Toolkit when the main question is measurement-system variation, and SPC Studio when the main question is process stability over subgroups.
Bring one messy engineering workflow into focus.
