In simple terms, the customer provides drawings as a way to ensure that the product meets expectations.

Disambiguation: Language descriptions (whether oral or written) are vague.

Define all the details: a complete part is not just the shape.It's clear on the drawing：

Precise size: the length, diameter, and angle of each part.

Geometric tolerances: such as flatness, verticality, concentricity, etc., which determine the accuracy and assembly performance of the parts.

Dimensional tolerance: The allowable deviation range of each size (such as ±0.05mm).

Surface treatment: if anodizing, sandblasting, polishing, etc. are required, and the grade is indicated.

Other technical requirements: such as heat treatment requirements, non-destructive testing (such as X-ray flaw detection), special cleanliness, etc.

Titanium alloy (such as TC4) is a difficult material to process, which makes its demand for processing guidance more urgent：

High strength and low thermal conductivity: This leads to high cutting force, concentrated heat, and fast tool wear during machining.The information on the drawing (such as chamfering and rounded radius) can help process engineers design better machining paths, choose special tools, and set reasonable cutting parameters to avoid burning the workpiece or losing the tool too quickly.

High chemical activity: Titanium can easily react with tool materials at high temperatures, resulting in work hardening.Clear drawings help to plan the process, reduce unnecessary processing steps, and control the temperature during processing.

High cost: Titanium alloy raw materials and processing costs are higher.Once you make a mistake, the loss of scrap is huge.Drawings are the first and important line of defense to prevent errors and waste.

Therefore, providing detailed and accurate drawings is the key first step for customers to ensure their own interests and ensure the success of the project. This is not only responsible for the processing plant, but also for the customer's own projects.
