Expanding upon the measuring devices introduced in our basic and intermediate-level courses, Advanced Measuring Tools covers techniques for the proper usage of Thickness Gauges, Inside Micrometers, Depth Micrometers, Dial Bore Gauges, and Hole Gauges. These advanced tools are used by most quality, tooling, machining, and maintenance personnel.

These courses are built on Routsis’s SkillSet™ training model, which combines instructional videos with hands-on learning and skills-development worksheets.

Over the course of 7 intensive training labs, participants learn the background, purpose, required equipment, and procedures for the correct usage of various measuring devices. Proper handling and storage of these sensitive tools is stressed throughout the training. Several of these labs cover field-checking procedures, which can be used to ensure your facility’s measuring devices are in proper operating condition.

Using Thickness Gauges

Sometimes called “feeler gauges,” these tools provide accurate measurements when employed properly. They’re commonly used for determining the gap between two mating surfaces — or for measuring the warpage of a flat surface. In this lab, the participant practices taking measurements with a set thickness gauges — to determine whether a specific part feature is within specification. The results of these measurements are documented on their worksheet.

Using an Inside Micrometer

Inside micrometers are commonly used in production environments. This lab covers the procedures needed to obtain accurate measurements. Participants use an inside micrometer to measure a particular part feature to determine if it meets the specification. By completing the worksheet associated with this lab, they also learn proper documentation procedures for such measurements.

Using a Depth Micrometer

In this lab, participants learn the correct handling and usage of depth micrometers. After watching videos that explain the purpose and objectives of the training lab, they practice measuring actual part features using a depth micrometer and logging the results on their worksheet.

Using a Dial Bore Gauge

Dial bore gauges are very helpful in making comparative hole measurements. In this training lab, participants determine whether a specific part feature is within specification, based on a dial bore gauge measurement, and record their measurements on the associated worksheet.

Using a Hole Gauge or Telescoping Gauge

These inexpensive tools are commonly used to determine whether a given hole dimension falls within the specified lower/upper tolerance range. In this lab, the participant will practice measuring a particular part feature using such tools and documenting their findings.

Field-Checking an Inside Micrometer

Micrometers are sensitive devices that can be susceptible to wear and damage in a rugged manufacturing environment. A “field check” provides a quick method of determining whether an inside micrometer is consistently delivering accurate measurements.

Field-Checking a Depth Micrometer

Like inside micrometers, depth micrometers can also be damaged and/or drift out of calibration. While a field check is no substitute for laboratory calibration, it provides a practical way to check whether the tool is functioning properly. This lab covers the equipment and procedures required to ensure it’s in good working condition.
