Large Machining Cost Calculation
Case Study 1: Identifying Critical Dimensions to Reduce Machining Costs
When reviewing the initial drawing for a large component project, Novelty Structures noticed that tight tolerances were specified across both functional interfaces and secondary surfaces. Machining every surface to uniform precision would have added substantial machine time without providing any functional benefit to the client.
Our team met with the client’s engineers to review how the component fit into the larger assembly. Together, we identified the key dimensions governing fit and alignment. We maintained tight tolerances on those critical locating features while opening up tolerances on areas where precision was less important.
This revision gave us greater flexibility when planning machining operations and eliminated unnecessary finishing passes. As a result, the client achieved clear savings in machining time and production costs, while all functional requirements were fully preserved.

Case Study 2: Maintaining Alignment on a Dual-Bearing Housing
Dual-bearing housing
On a project involving a large bearing housing designed to support a single shaft across two internal seats, the drawing specified tight tolerances across the entire exterior of the housing block.
During our technical review, Novelty Structures pointed out that tight control over external clearance faces did not affect shaft alignment or bearing performance. The essential requirement was the relationship between the two internal bearing seats: their diameters needed to provide the exact fit, and their axes needed to align accurately to prevent binding.
We worked with the client’s engineering team to classify the bearing seats and their reference datums as the sole critical features. The updated drawing retained strict fit and alignment requirements for the seats while relaxing tolerances on external surfaces. This allowed our shop floor to sequence operations around the functional interfaces and focus inspection on seat alignment and bore dimensions.
Case Study 3: Resolving Deep-Hole Tolerances on a Three-Metre Shaft
During a project involving a three-metre-long shaft, Novelty Structures identified a manufacturing issue with a tight tolerance specified along the full depth of a deep internal bore. Holding that degree of precision continuously over a three-metre length was unfeasible with standard deep-hole tooling.
We reviewed the application with the client’s engineers to clarify where the precision was functionally necessary. The review revealed that the mating shaft component only engaged tightly near the opening of the hole.
Both teams agreed to revise the drawing, applying the tight tolerance strictly to the final 100 mm at the edge of the hole while allowing wider tolerances along the remaining depth of the shaft. This change preserved the precision required for fit and assembly while establishing a reliable, straightforward machining process for the rest of the feature.
