Mill Operations & Industrial Engineering
Identifies the resonant danger band of a spinning spindle: first critical speed from mass and bearing stiffness, operating speed ratio, dynamic amplification and whirl amplitude at running speed, the amplitude that would occur at resonance and the speed band to pass through quickly.
Calculator
Industrial Engineering, Time & Motion
Converts material movement into labour cost: time per trip from distance and handling, daily minutes and distance walked, daily and annual cost of the movement, the share of trip time that is walking, and the saving a target distance reduction would deliver.
Calculator
Mill Operations & Industrial Engineering
Profiles the inertial loading a reciprocating sley imposes: peak acceleration at front dead centre in m/s² and g, peak inertial force, the smaller back dead centre force, the alternating component driving frame fatigue and the oscillation frequency.
Calculator
Industrial Engineering, Time & Motion
Quantifies cross-training depth and absence resilience: polyvalence index from the skill matrix fill rate, average skills per operator, trained operators per operation, expected availability after absenteeism, the minimum training required for coverage and the redundancy factor achieved.
Calculator
Mill Operations & Industrial Engineering
Predicts when a sizing cylinder coating will fail: mechanical wear from yarn contact adjusted for pressure, thermal cycling wear, total loss and thickness remaining, and the operating hours left before the coating reaches its failure thickness.
Calculator
Mill Operations & Industrial Engineering
Decides between displacement and draining at a size box changeover: box turnovers and volume needed to bring the recipe inside tolerance, washout time, the drain-and-reheat alternative, time saved and the size liquor a drain would have discarded.
Calculator
Factory Physics & Assembly Logistics
Sizes weaving shed extraction against both criteria: ventilation flow from air changes, dilution flow from the dust load and permitted concentration, the governing figure in CFM, and the fan power it will draw.
Calculator
Factory Physics & Assembly Logistics
Sizes waterproof seam tape: overlap achieved either side of the stitch line, the hydrostatic resistance that overlap supports, hot-air nozzle dwell at line speed, tape consumed per garment and the width a target head would need.
Calculator
Mill Operations & Industrial Engineering
Predicts when a lockstitch machine needs service: speed acceleration factor, hook timing drift and thread tension drift accumulated over running hours, current working tension, and the hours until each tolerance is reached.
Calculator
Factory Physics & Assembly Logistics
Quantifies the marker waste caused by roll width variation and how much of it width banding recovers: waste width and percentage with and without grouping, the area saved and what it is worth.
