CMM Inspection, Reverse Engineering and Lead Times in Lodi: GMK Machining

A buyer’s first question about a machine shop is often about quality. The second is about time. Buyers in Lodi who supply aerospace and defense customers need to understand both, since delays and errors are costly. GMK Machining, Inc. is listed here for CNC milling, CNC turning, 5-axis machining, assembly, CMM inspection, reverse engineering, engineering and design, plastics machining, aerospace, defense, horizontal machining and family ownership. This page explains how inspection, reverse engineering and scheduling fit into a machining order.

Why inspection matters

Inspection confirms that parts match the drawing. A coordinate measuring machine, or CMM, uses a probe to measure points on a part and calculate its dimensions. It can check hole positions, flatness, angles and other features. When a customer requires proof, the CMM produces a report.

Pallet and horizontal milling

Horizontal mills with pallets let a machine keep working while new parts are loaded elsewhere. They suit batch work and repeat orders. Buyers who need steady production should ask how orders are scheduled.

Reverse engineering

When a part has no drawing, a shop can measure it and build a model. With a CMM and CAD software, this can be done accurately. Provide the part, the machine it came from and an explanation of how it is used. Ask for the resulting drawing and model.

Prototype and production

Prototypes check the design. Production fills orders. Because aerospace and defense programs often evolve, flexibility matters. Share your forecast, even if it is approximate.

Understanding turnaround

Turnaround is the time from order to delivery. It depends on material availability, machine load, the number of operations and any outside processing. A typical figure from a shop is only a guide. Ask for a specific date on your order, and ask what could change it.

Owner involvement

In a family owned shop, owners may review each project. That can improve communication and accountability. Buyers can ask who will be their contact and how they will be updated on progress.

Materials

Aluminum, steels, brass, copper and plastics are common. Aerospace work may need certified material, so say what paperwork you need. Material certificates show what the metal is and where it came from.

Software and models

Shops use CAD and CAM software to produce programs. If you can supply a native or exchange format model, the shop can reduce the time spent recreating it. Keep your drawing and model consistent, so the shop does not have to guess which is correct.

What to include

• Drawing with revision and tolerances
• 3D model in a common format
• Material and certification needs
• Inspection and reporting requirements
• Quantity, schedule and shipping location in Lodi or elsewhere

Planning a long lead job

Complex parts can take weeks. Buyers can help by approving quotes quickly, placing orders early and giving advance notice of changes. A realistic schedule reduces stress for everyone.
