The design, manufacture and use of springs can be traced back in time to the Bronze Age. Spring design is a science based on complex arithmetic calculations combined with material science. Springs are used in everyday consumer devices including cellular phones and computers, they are used widely in industrial applications including automotive and aerospace, they are used in precision medical devices where a spring, having a diameter of 0.0036 inch (about equal to the size of a human hair), is used in catheters and endoscopic instruments. While the wheel is often considered one of the most important inventions ever, the spring is arguably as equally important and with spring design constantly evolving and requiring more advanced testing and tolerancing.
Determining a spring’s characteristics and validating a spring’s performance is critical to ensuring that the spring will perform to its specification over its intended life-cycle for its intended application. This following video will introduce the latest measurement technology from the L.S. Starrett Company, designed to ensure accurate, precise, repeatable and reliable testing of helical compression and extension springs using its innovative SMS Series Spring Testing Systems.
The Starrett L2 Plus Series software is designed for advanced force measurement and analysis, used with FMS and FMD Series force testers.
It has been optimized for quality control and engineering personnel.
Operating on an all-in-one L2 Plus Workstation, it can be use for
tensile, compression, cyclic, flexural, peel, friction and shear testing.
Test setup is easy and graphical. Tests are created using a suite of
test step types with each step having attributes that you configure
including limits, step speed, etc. Once your test is created, you
perform the test and L2 Plus displays a large graph of your test data.
Next, use the many analysis tools to measure and display results,
e.g. points, slopes, minimums, maximums, peaks, valleys, averages,
Display results on the graph or in data tables complete with
tolerances. Tabular results can include statistical w. A set of standard
reports can be printed for graphs, tables, statistics, tolerances and

The Starrett MVR Series manual vision metrology systems are ideal for individual measurements or short runs. They are available with dedicated 6.5:1 zoom optics or a quick-change bayonet lens mount which accepts zoom optics or telecentric lenses for micron-level resolution and optical distortion down to 0.001% for accurate field-of-view (FOV) measurements.These can encompass an entire small part up to 2.00" x 1.50" or a feature of a larger part and be seamlessly integrated with stage motion to measure parts with a length up to 8" (MVR200) or 12" (MVR300).
MVR Series hardware features include a granite base for maximum stability, recirculating ball linear guides for smooth and precise stage motion, and a motorized Z-axis with variable speed control. All electronics other than the PC are housed in the Z-column, ensuring an integrated system with minimal external wiring.

Our new material testing systems answer the need for more advanced testing while continuing our objective of supplying solutions that are easy-to-use without compromising functionality. Our objective of providing an affordable solution that meets the technical demands of engineers and research scientists without compromising testing methodology or functionality is demonstrated in our new L3 software and associated MMS and MMD Series material testing systems.
Look at a Starrett material tester and you immediately see we’re different. Some features are very apparent, granite bases and extruded aluminum columns for optimum stiffness. Less obvious are high resolution encoders, precision, preloaded ball screws and advanced electronics that let you sample up to a true 5kHz and interface with digital and analog I/O devices. Axial frame stiffness, precision, accuracy and machine lifecycle were paramount in our design. The result is our family of single and dual column material testers designed to improve your testing and analysis capabilities, providing consistent, accurate results for years to come.
The Starrett AVR Series CNC automatic vision metrology systems are ideal for repetitive measurements and automatic comparison to CAD files. They are available with dedicated 6.5:1 zoom optics or a quick-change bayonet lens mount which accepts a choice of telecentric lenses for micron-level resolution and optical distortion down to 0.001% for accurate field-of-view (FOV) measurements. These can encompass an entire small part up to 2.00" x 1.50" or a feature of a larger part and be seamlessly integrated with stage motion to measure parts with a length up to 8" (AVR200) or 12” (AVR300).
AVR Series hardware features include a granite base for maximum stability, recirculating ball linear guides for smooth and precise stage motion, and full CNC control for high throughput. All electronics other than the PC are housed in the Z-column, ensuring an integrated system with minimal external wiring.
Starrett 505 Series Protractors take error-prone calculations out of miter cuts. Simply set your saw to the angle that you read and transfer readings directly to the miter saw. The CP505 has additional functions including the ability to handle complex angles required to provide a perfect fit for crown moldings.
A Perfect Crown Molding
with your Starrett 505A-12:
- Measure the corner angle near the ceiling. Note the Miter Cut value from the dial (inner scale).
- Determine the spring angle (information available where you purchase your crown molding stock).
- Refer to the compound cut conversion table. Locate the row with the same "Miter Cut" value as your corner measurement.
- Note the "Miter Angle" and "Bevel Angle" from the row that corresponds to the spring angle of your work piece stock (38° or 45°).
- Refer to the table and carefully set the miter angle and bevel angle on your compound miter saw, then position your work piece with reference to the blade and fence, as indicated. Then, cut your first work piece.
- Reset the saw and position your second work piece. Then, cut your second work piece.
- The two pieces should align perfectly for your crown molding!

Since its introduction over 100 years ago, the rubber extrusion industry has progressed through several generations of technology for profile geometry measurement. Off-line optical comparator methods were popularized over 50 years ago. These technologies enabled users to characterize the dimensional quality of samples, but could not characterize the quality of a population as a whole. Recent advancements in on-line technology enable precise and continuous characterization of the dimensional quality of complex profiles. These empower users to implement several value-creating programs:
1. In-line measurement can be used to continuously monitor the dimensional quality of any profile, and alarm the operator when any problem occurs. This can identify problems not possible with periodic off-line checking.
2. In-line measurement can be used during the startup of any run to assist in reducing the time required to reach stability.
3. In-line measurement can be used to quickly evaluate all lines in the factory to identify cyclical conditions that would affect all profiles. Remediation of such problems will benefit all profiles run on each line.
4. In-line measurement can be used to assist tooling development. Snapshot files can be exported as .dxf point files that can be opened in the die design CAD application and compared to the intended design. As die trials are run, on-line measurement can be used to see how stable the process behaves in production. This information can be used to optimize the extruder setup.
5. In-line measurement produces data histories that can be used to compare any run with its historical performance, and verify the effect of quality improvement initiatives.
