CAM and engineering consultancy by a
McLaren Racing and Alpine F1 programmer.
14 years at the top of the industry — now working for you.
Full 5-axis CAM programming in HyperMill — from rapid prototyping through to batch production. Programs are produced to the same verified standard used in Formula 1, drawing on professional experience with VERICUT simulation gained at Alpine F1 Team. Production-ready NC code delivered to your machine, not just your inbox.
5-AXIS SIMULTANEOUS
Design for Manufacture
A full written design breakdown assessing the machinability of your components before they reach the shop floor. Wall thickness, tool access, datum strategy, tolerance risk — we find the issues that cause expensive re-designs downstream.
Comprehensive fixture design for any volume — one-off components through to batch loads of 20+ parts. Every project is delivered with a full written report and production-ready 3D models, ready for manufacture or quotation.
Custom post-processor development for 3-axis CNC machines. We build, test, and validate posts that output clean, reliable G-code for your specific controller and machine configuration — so your programmers focus on programming, not firefighting.
Amethyst currently provides CAM programming to Alpine F1 Team. The same standards, workflow, and attention to detail — available to you.
Start a ProjectAmethyst Precision Engineering was founded by James Mannings — a CAM programmer who has spent his career at McLaren Racing and Alpine F1 Team, and as a Manufacturing Engineer at HeliMods in Australia.
The company is named after HMS Amethyst, the Royal Navy frigate on which James's grandfather served during the Korean campaign. Precision, resilience, and performing under pressure — values that run in the family.
