“…Such systems replace the need for manual gauging necessary for workpiece alignment, tool length calculation, datum setting and in the case of +5-axis systems tool rotation-centre point control [10]. OMP systems can also be used to monitor the size of the features being machined, to validate the part movement, distortion, and feature dimensions [8].…”

“…A reduction in the reliance of CMMs is likely to result in benefits associated to cost and time saving, pro-active process control, elimination of non-value adding tasks and agile manufacturing, as indicated by Table 1. Table 1 -Benefits associated to on-machine inspection [1], [5], [8] process has performed as expected and produced the correct part geometry. Advantageously, non-conformance can be detected closer to the point of feature creation, and if necessary reworked, in-situ.…”

“…For high-precision monolithic products CMMs are the only measurement systems capable to perform with an acceptable level of uncertainty [7]. Manufacturing engineers are often frustrated by CMMs as they are a major source of process bottlenecking and inefficiency [5], [8]. As the need for more adaptive and data driven manufacturing increases the feedback delay from the CMM to the machine tool is generally regarded as unacceptable.…”

High precision manufacturers continuously seek out disruptive technologies to improve the quality, cost, and delivery of their products. With the advancement of machine tool and measurement technology many companies are ready to capitalise on the opportunity of on-machine measurement (OMM). Coupled with business case, manufacturing engineers are now questioning whether OMM can soon eliminate the need for post-process inspection systems. Metrologists will however argue that the machining environment is too hostile and that there are numerous process variables which need consideration before traceable measurement on-the-machine can be achieved. In this paper we test the measurement capability of five new multi-axis machine tools enabled as OMM systems via on-machine probing. All systems are tested under various operating conditions in order to better understand the effects of potentially significant variables. This investigation has found that key process variables such as machine tool warm-up and tool-change cycles can have an effect on machine tool measurement repeatability. New data presented here is important to many manufacturers whom are considering utilising their high precision multi-axis machine tools for both the creation and verification of their products.

“…In the same way, Corrigall et al [13] proposed a method based on probe approach directions (PADs) to determine how the probe and the component should be set up on the machine. Moreover, techniques such as fuzzy set theory, Hammersley's algorithm, Zmap, etc., have been implemented by Cho et al [14] to determine number of measuring points, their locations, and optimum probing paths as well as possible collisions during the inspection run. Zhang et al [15] described inspection process planning system to produce an inspection process plan directly from the CAD model.…”

Coordinate-measuring machines (CMMs) have widely been utilized for performing inspections due to its high precision and accuracy. With increasing complexities of parts and tighter tolerances, there is a need of well-defined strategies and techniques to effectively plan inspection process for CMMs. The proposed work comprehensively describes different steps to generate an instruction file which can finally be executed on CMMs for efficient measurement. This work which commences with feature extraction and recognition followed by generation of probe approach directions for accessibility, setup planning to get part orientation, determination, and distribution of touch points on features including other activities leads to an effective inspection plan. The inspection plan is then used to produce DMIS file which after post-processing is executed on CMM. A series of techniques and algorithms such as clustering algorithm, graphical method, artificial neural networks, and algorithms for generation of touch points have been utilized to accomplish efficient inspection on CMM. The effectiveness of proposed strategies and techniques has also been verified through a part case study.
