Frequently asked questions

Below you will find some of the commonly asked questions regarding NC-PerfectPart.

Yes. NC-PerfectPart uses pre-prepared probe paths to measure your part where it really is and automatically adjust the controller’s workspace without manual intervention.
Yes. The NC-PerfectPart system not only eliminates concessions, but scrap and rework due to poor or variable fixturing. It is 100% accurate, removes part-to-part variation and is an important tool in any quality improvement program as well as eliminating scrap.
Setup time is reduced typically by 70% for complex parts. Typically, it takes less than 10 minutes to fixture parts. Although some examples are more impressive; Airbus parts we reduced from 3 hours to 1.5 minutes, the BAE Systems Eurofighter Typhoon foreplane was reduced from 7 days to 38 minutes. The actual time is dependent on how much probing is required and how complex the part is.
It is not variable, it is fixed. Once setup, NC-PerfectPart takes exactly the same time every time. This gives you the opportunity to accurately plan your schedules and meet your own customer’s deadlines.
NC-Checker provides the ability to quickly verify the machine tools performance has remained constant before any operation.
NC-Checker allows you to check the state and capability of a machine prior to a maintenance visit, and then again after the visit to confirm it’s state has improved. Frequently maintenance can lead to machining issues where the engineer has had to replace parts and then not set them up, or recalibrated them to the state they were in before the visit.
You can have confidence your Probe has been calibrated accurately. If you are using your probe for any kind of setup, not just NC-PerfectPart. You need to know it has been accurately calibrated or you could get results worse than manual clocking methods.
NC-Checker includes MSP’s world-class 5-axis probe calibration derived from technology we developed for Renishaw’s Revo probe.
Yes. NC-PerfectPart looks after the alignment adjustment so only a generic clamping fixture is required. These could be simpler “relaxed” fixtures to eliminate fixture distortion causing machining errors.
Expensive bespoke fixturing or tooling is no longer necessary. For shops with many and various parts to make it greatly reduces your fixture storage requirement.
Unknown to manufacturers, some raw parts are incapable of being machined accurately because there is not enough material available. You could never machine these parts accurately. However, all other parts that follow our process are accurate.
It is excellent for the problems that composite work throws up. NC-PerfectPart has many features for compensating for uneven surfaces. Hole Offset compensation, counterbore compensation and surface offset machining compensation are all features of the standard system.
Case study
Yes. Your machine’s geometric performance can be tracked across any time period. Day-to-Day, month-to-month, or even hour-to-hour. For example, you could track performance over a 24 hour period to see the effect of temperature changes.
You can with NC-Checker. Our 5-axis calibration means you can confidently use whatever probe orientations you need to access the areas of the part that needs probing.
A comprehensive machine benchmark before moving a machine gives you a reference point. This can be used to compare against after the machine has been moved by running the comprehensive machine benchmark again. You can then be confident the relocation has had no effect on the machining quality of your machine.
Frequently new machines are left with kinematic problems by the vendor because they do not leave the machines parameters tuned correctly, or differently to the needs of your work. A common example is TRAORI on a Siemens 840D, which should be 15-25 µm tolerance, but often gets left set at 50 µm. This is far too high for complex 5-axis work, but machine vendors tend to be unaware of this fact.

A full NC-Checker machine benchmark on a new machine after the vendor thinks it is setup is a fantastic way of ironing out these issues. Example issues include the head, or rotary table rotation, axis parallelism or tool loader. All be revealed in a tabulated hard copy form for evidence, as well as many more settings and measurements.

The advantage for the vendor is that the engineer is at your site, he is next to the machine and the changes he needs to make usually take seconds. Doing this the traditional way involves months of work machining with a sense that all is not well, weeks of argument with the vendor, organising a visit for a random overhaul – because nobody really knows what the problem is, even you. And the vendor engineer on-site for long periods of time.
