In CNC programming, precision and safety are determined long before the cutting tool meets the workpiece. One of the most important steps in ensuring successful machining is configuring the Worksetup correctly. CAPSturn provides a dedicated Worksetup interface that helps machine programmers define all the essential parameters for a safe and efficient manufacturing process.

Setup Data 1: Defining the Machine setup

The first step in any setup involves specifying the physical conditions under which the part will be machined. It encloses the part inside a safety area to avoid collisions.

In this tab, the programmer defines:

1. Units: Selection of MM or Inch as the measurement system, which is fundamental for correct programming.
2. Workpiece Material: Specifying the material type (for example, Aluminium alloys – high silicon >16%) allows the system to suggest optimized cutting parameters.
3. Holding Method: Choice between Internal or External holding, depending on whether the part is gripped from the outside or inside.
4. Part Load + Unload Time: Estimation of handling time for the part to be loaded and unloaded, useful for cycle time calculations.
5. Limiting Spindle Speed: Defines the maximum spindle RPM to avoid excessive rotation that could cause safety risks or material damage.
6. Clearances: Safety clearances are specified in the Z-direction, Inner Diameter (ID), Outer Diameter (OD), and the left face to prevent tool-part collisions during machining.

This tab ensures that the virtual setup is aligned with the actual conditions on the Machine, reducing the risk of errors and ensure safe machine process.

Setup Data 2: Tooling and Machine Configuration

In the second tab, you configure the machine's tooling logic and turret positioning.

Key settings include:

1. Tool Change Position: Defines safe X and Z coordinates for the machine to switch tools at both the front and rear turrets.
2. Program Mode: Selection of either Radius or Diameter mode, which controls how dimensions are interpreted in the CNC program.
3. Default Turret Position: Selection of the turret (front or rear) that will be used as default for operations.
4. Tool Mounting Orientation: Defines whether the tool is mounted Face up or Face down — an important factor for accurate simulation and collision avoidance.
5. Jaw Size: Specifies the dimensions of the chuck jaws, including Jaw height and Jaw length, which is critical for avoiding tool interference during machining.

This setup ensures smooth coordination between the programmed tool paths and the actual machine environment.

Documentation: Recording Setup Information

Good documentation is essential for traceability and repeatability in manufacturing. The Documentation tab allows the programmer to store important job-related information, such as:

1. Part Number / Name: Unique identifiers for the part.
2. Setup Number: A version number or revision ID for the specific setup.
3. Fixture: Details about the work holding fixture used for the operation.
4. Programmer: The name of the programmer responsible for the setup.
5. Remarks: Space for any additional notes or special instructions for operators.

Accurate documentation helps ensure smooth handovers between shifts, prevents miscommunication, and supports quality control and audits.
