CMM Inspection ( ARM / Laser Tracker )
Portable CMMs ( Arm Type CMM ) simplify the implementation of geometric dimensioning and tolerance (GD&T) and provide efficient, easy-to-use solutions for CAD-based 3D inspections and nominal comparisons.With their versatile contact and non-contact measuring capabilities, tools such as the Arm , 3D Scaner and Laser Tracker can utilize CAD overlays to check complex geometry against design or CAD comparison to evaluate deviations in surface form and ensure every part is machined to an exacting tolerance
Machined parts come in a diverse range of shapes and sizes, and flexible 3D metrology tools for part inspection and dimensional analysis are required to verify their accuracy and quality.Many machine shops are now equipped with portable CMMs such as measuring arms and laser trackers. These meet a variety of dimensional measurement needs, such as on-machine and in-line inspection and CAD comparison, to ensure proper tolerances are achieved
FIRST ARTICLE INSPECTION
First article inspection is an essential part of quality control in manufacturing. Inspecting a pre-production sample confirms whether or not the part meets all engineering, design and specification requirements.
Portable CMMs from FARO offer 3D measurement solutions to help streamline this process. Portable metrology equipment, including measuring arms and laser trackers can quickly capture a prototype part’s surface form and geometric features which can be compared to nominal data in a CAD file or used as a digital record to meet the company’s first article documentation requirements.
In the past, machine shop inspection has required the removal of parts from a CNC machine to a temperature controlled inspection area for surface inspection or dimensional inspection of the part. This is time-consuming and expensive. Fortunately, incorporating portable CMMs from FARO® directly into production lines can streamline this process.
The portability of FARO’s 3D metrology tools, like the measuring arm, enables efficient in-line, in-process and on-machine inspections. This delivers consistent, accurate measurements directly on or at the machine producing the parts.
Identifying defective parts from suppliers upon arrival allows companies to establish and maintain strict quality standards. Implementing a comprehensive incoming inspection process prevents defective parts from making it to assembly, eliminating costly scrap and rework later.
By integrating portable CMMs such as measuring arms into the receiving inspection process, operators have a quick and efficient way to determine whether or not these parts meet specification and design requirements.
LARGE PART INSPECTION
In many industries such as aerospace, automotive, and heavy equipment manufacturing, large-scale measurements are a common requirement. Given the large scale of various components in each of these industries, consistent, accurate measurements are necessary to maintain design intent and performance; however, taking large-volume measurements can be a cumbersome and slow task.
Laser Tracker’s groundbreaking large volume metrology tools, such as the Laser Tracker streamlines the entire inspection process. Quickly taking precision measurements at any scale, portable metrology solutions provide the highest accuracy with the least amount of user variability, eliminating costly rework and scrap.
