RADISH CALIBRATION PROTOCOL

Industrial Engineering meets botanical precision. Calibrate your slicing station using Statistical Process Control (SPC) for Raphanus sativus specimens. Every cut is a data point.

Moisture Content 95.0 1.0 % wet basis
Color Intensity 78.0 3.0 a* (CIELAB)

SPC Calibration Engine

Enter your batch measurements. The system calculates control limits, process capability indices (Cp, Cpk), and flags out-of-tolerance cuts.

Process Capability (Cp)

0.00

Target: ≥ 1.33 for capable process

Process Performance (Cpk)

0.00

Accounts for mean shift

Control Limits (±3σ)

UCL: 0.00

Center Line: 0.00

LCL: 0.00

Formula: Cp = (USL - LSL) / (6σ)
Formula: Cpk = min[(USL - x̄)/(3σ), (x̄ - LSL)/(3σ)]

The Science Behind the Slice

At the food-processing plant in Stevens Point, I calibrate sensors that measure exactly these parameters. But here, I'm applying the same rigor to my art practice. Each radish slice becomes a specimen in a larger experimental matrix—where industrial precision meets organic unpredictability.

Why SPC? Statistical Process Control isn't just for assembly lines. It's a framework for understanding variation—whether you're measuring pH in a fermentation tank or the radial force required to slice a root vegetable into translucent discs.

The Neon Connection: When I sketch process flows in neon colors, I'm visualizing control charts. Each stroke represents a data point. Each hue shift marks a deviation from target. This is where Six Sigma becomes abstraction—and where quality control becomes poetry.
