Printed paper schedules are obsolete within 30 minutes. Synctile updates TV kiosks across the factory in real time.

Implementation Speed

ERP implementations take 6 to 12 months. Synctile is fully running on your shop floor in under one afternoon.

Frequently Asked Questions

Common questions about manufacturing calculations, formulas, and visual shop floor planning.

Are these manufacturing calculators completely free to use?

Yes. All Synctile engineering calculators and shop floor tools are 100% free to use online with no registration or software download required.

How do these tools integrate with shop floor scheduling?

Calculators like Laser Cutting, Shop Capacity, Takt Time, OEE, CNC Cycle Time, and SMED establish target pace, machine availability, and setup benchmarks for your factory. Synctile uses these exact mathematical principles in its digital drag-and-drop scheduling boards to prevent workstation bottlenecks and over-allocation in real time.

Can I use these tools for high-mix, low-volume job shops?

Yes. Each calculator includes tailored industry presets for high-mix CNC machine shops, precision fabrication bays, automotive assembly, stamping presses, and electronics manufacturing.

What is the difference between Takt Time and Cycle Time?

Takt time is the rate at which you must produce units to satisfy customer demand (customer pace). Cycle time is the actual time required for an operator or machine to complete one unit (manufacturing speed). If cycle time exceeds takt time, line balancing or parallel stations are required.

How does SMED setup reduction increase machine capacity?

SMED (Single-Minute Exchange of Die) separates internal setup (done while machine is stopped) from external setup (done while machine is running). Converting internal setup tasks to external setup reclaims hundreds of spindle hours per year, directly expanding machine capacity without buying additional equipment.
