Topic 1:  If you haven’t signed up yet, now is your chance.  Harold mcCormick will be conducting a SAE class on Piston and Ring Design/Materials, with a focus on recently developed materials on cylinder finish quantification and oil ring tension measurements.  this course is currently scheduled for thursday-Friday, October 2-3.  Contact the SAE Learning Center at to register.

Topic 2:  Customers that use the CKE SEE 3-D Three-Dimensional Surface Evaluation service provide a wide range of cylinder and piston sizes to analyze.

the CKE SEE 3-D System has the capability to analyze very large and very small cylinder and piston surfaces.  Recently the ranges were from 1.45″ to 17.75″.  Will Pisoni and Josh Mandernach (Cke Engineers) are seen here using the SEE 3-D replicator in a large cylinder.  Will also conducted piston groove finish analysis on the piston shown below which fits inside the palm of your hand.


The SEE 3-D® “I” Industrial system is designed to examine the surface finish in very small bores that are difficult to measure.  With this device, CKE has created a surface measurement system that can reach where no profilometer can.  This replicator is practical for use by operators on the production floor.  (Range 0.37″ and above)


The SEE 3-D® “A” Automotove system measures small and large bores typically found in the automotive and large diesel industries.  The replicator is designed to be flexible and adjust to all sizes of cylinders both vertically and horizontally.  (2.5″ and above)


Topic 3:  the CKE See 3-D Three-Dimensional Surface evaluation system not only quantifies over 30 specific finish values, but also quantifies torn and folded material as well as porosity and cross hatch angle.

Torn and folded material can disrupt proper sealing or act as an abrasive that leads to premature wear in an engine.

Work done recently for a CKE customer using the SEE 3-D Surface Evaluation System enabled CKE to expand and further automate the ability to identify and quantify torn and folded material using proprietary algorithms that can replicate a standardized manual process with greater precision and far less time.  See TR Report 359TFMcomparison

The CKE SEE 3-D Three-Dimensional Surface Evaluation system is offered to customers in 3 ways:

1.  As a product for sale which includes the replication unit, the ZeGage interferometer and Windows 7 computer with CKE proprietary SEE 3-D software.

2.  As a Service whereby the customer can purchase the replicator and replicate materials.  Make the replicates in house and have CKE profide the analysis.

3.  As a service whereby the customer can send the cylinder blocks to CKE for replication and analysis.

See CKE SEE 3-D product information.

CKE will begin producing monthly newsletters starting this month, August, 2014.

CKE appreciates the opportunity to provide Cylinder Kit tecnhologies, products and services.

CKE announces SAE 2-day seminar, October 2-3 on Piston Ring Design/Materials conducted by Harold McCormick

Contact the SAE Learning Center at to register for the class.

Learning objectives

By attending this seminar, you will be able to:

  • Describe the function of each ring and its interaction with other components within the cylinder kit to provide oil consumption and blow-by control
  • Identify available computer models and instrumentation that is available to predict and measure the function of each of the components in the cylinder kit on oil consumption and blow-by control
  • Compare the base systems and facing material systems and the trade-offs associated with each of the material systems, i.e., wear rate, scuff resistance, etc.

Who should attend

If you are an engineer associated with engine design and development and interested in understanding the function and design considerations within the cylinder kit system, you would benefit from attending.


Participants should have an undergraduate engineering degree and some exposure to piston ring design and materials.

Topical Outline

  • Background
    • Evolution of piston ring designs/materials — diesel engines
    • Evolution of piston ring designs/materials — gasoline engines
  • Outline of nomenclature and ring design methodology, including referencing to various published standards i.e. — SAE, DIN, ISO
  • Systems parameters and their interaction with piston rings to cause variations in performance
    • Cylinder bore geometry
    • Cylinder bore finish
    • Piston design
    • Power density
    • Operating speed
    • Engine Lubricants
  • Typical procedures and equipment employed to measure dimension properties of piston rings
  • Developed models aiding cylinder kit design
  • Determining the effect of design parameters on oil consumption, ring function, cylinder bore distortion, friction and wear rates — unique test set-up procedures and their utilization

Instructor:  Harold McCormick

Harold McCormick is currently President of C-Engineering, Inc., an engineering firm specializing in providing analysis instrumentation gauging and other consulting services for engine and lubricant manufacturers.  He was formerly Director of Engineering, Ramsey Plant TRW-Valve Division, with ongoing responsibililty for research and product engineering.  He has also completed 57 graduate hours in Applied Mechanics and Metallurgy at St. Louis University. His experience has involved directing substantial work to develop models/test procedures and test fixtures that can be to predict wear in severe wear applications such as piston rings, engine exhaust and valve seats as well as severe dry sliding wear applications.  He holds more than 40 U.S. patents and has authored or co-authored numerous technical papers for the SAE International as well as other automotive engineering organizations.  Mr. McCormick holds a B.S. in Mechanical Engineering from University of Missouri – Rolla and a M.B.A from St. Louis University.
