Description
Japanese manufacturing automation company ARUM developed TTMC Origin, a machining center operated through natural conversation with an LLM-powered AI character named KAYA, using Azure Speech, Azure OpenAI and Azure AI Search with GPT-5 running on an industrial PC. Users with no machining knowledge can perform high-precision operations by voice chat. Automating NC programming cuts the steps with CAM from 177 to 2, and since NC programming accounts for 50% of production cost per part, ARUM says automating it could cut production costs in half.

Problem
Japan has over 200,000 metalworking companies, but the number of skilled workers in the industry is dwindling drastically. ARUM had automated NC program generation and machining processes, but the many buttons on its tools still hindered effective use among inexperienced users.

Solution
ARUM developed TTMC Origin, a machining center operated through natural conversation with the LLM-powered AI character KAYA. An LLM (GPT-5) running on an industrial PC in the machining center controls KAYA, which integrates with Azure services: Azure Speech for voice communication, Azure OpenAI for summarizing and interpreting conversations, and Azure AI Search for database searches. Foundry Agent Service on the Microsoft Foundry platform provides a fallback generic AI in case the primary AI function does not perform as expected. KAYA also integrates with TTMC Brain, which, based on the conversation, automatically generates a program for the machining process and autonomously controls the machining center.

Business value
TTMC Origin decreased NC programming steps with CAM from 177 to 2. Because NC programming accounts for 50% of the production cost per part, ARUM's General Manager says automating this stage could cut production costs in half. ARUM says reservations open in July 2026 with inquiries already flooding in, and it plans to release the solution overseas gradually from 2027.
