Closed training

SPC – Statistical Process Control

SPC – Statistical Process Control

SPC – Statistical Process Control

  • Process improvement
  • DURATION: 2 days / 16 hours

Scope

The major part of the training are workshops consisting the analysis of inspection results with the use of SPC tools. Training participants create and analyze control cards (based on real data). They also learn to use ability indices as practical as possible – if possible on their own data.

The basic goals of the training are:

  • Preparation of participants to analyze the behavior of processes with the use of basic statistical tools.
  • Discussion of the practical use of control cards.
  • Discussion of the method of evaluating processes and machines with the use of capability indicators.

Information about the program

CONTENTS:

  • Introduction to the use of statistics in industry
  • Statistics and the quality management system.
  • Differences between quality control and process control.
  • SPC and standards (PN, ISO, industry standards).
  • ISO 8258 – SPC basis.

CONTENTS:

  • Basic statistical measures used in SPC.
  • Stratification and Paynter Chart.
  • Using a histogram to evaluate the process.
  • Special and random disturbances in the process – where they come from and how to identify them

EXERCISES:

  • Determination of basic statistical measures;
  • Create a histogram for sample data;
  • Process behavior analysis using histograms – practical cases

CONTENTS:

  • Normal distribution and the “3s” rule.
  • Why is the Normal Distribution so important in SPC?
  • Methods of data normality testing (analytical and graphical tests).
  • Assessment of defectiveness of processes with the use of normal distribution.

EXERCISES:

  • Examination of the normality of the distribution (graphical method);
  • Assessment of the type of distributions based on probability plot – practical cases.

CONTENTS:

  • Construction of the control card and the differences between the control limit and the tolerance limit.
  • Control cards when analyzing data from the process – basics of construction.
  • Basic cards: X-R / S, IX-MR, Me-R.
  • Cards for alternative assessment (p, e.g., u, c) – examples of applications.
  • Special cards (e.g. for short series) – overview.

EXERCISES:

  • Creation and interpretation of control charts (X-R and / or IX-MR);
  • Creation and interpretation of control charts for attribute data;
  • Behaviour analysis of the process with the use of number cards – practical cases.

CONTENTS:

  • Basics of qualitative ability assessment.
  • Machine Capability Test (Cm / Cmk).
  • Process capability and performance testing (Cp / Cpk, Pp / Ppk).
  • Capability and process stability – differences.

EXERCISES:

  • Determination and analysis of process and machine capability indexes;
  • Process capability interpretation;
  • Comparing processes using Cp and Cpk

Additional information:

During the training, several exercises are carried out, including: calculating basic process statistics, testing the normality of the distribution of results, creating and analyzing control charts, calculating and analyzing the capabilities of processes and machines (including Cp and Cpk).

Participants will receive worksheets that they can later use as part of their company’s statistical process control application.

After the training, each participant will receive a certificate confirming completion of the training.

Addressees:

People responsible for the use and development of the use of statistical methods to control processes. Technologists, process engineers and quality management representatives.
