1 Expert cut This chapter's purpose is to help the in his first steps with Lantek Expert programming system. This chapter includes:
1.1 FOLDER/JOBS The Folders can be created to manage various jobs. To work with Folders, you have to enable the Job explorer parameter. This Job explorer option provides the list of folders and Jobs that are created. One can create a folder inside another folder. Any new jobs created can be organized in folders in a tree structure shown on the left side of the in the CAM window.
1.2 CREATING A FOLDER/JOB 1. Execute the main program: Start - Programs - Lantek - Lantek Expert CAM 2. Once inside the main program of Expert, Select the option Job explorer: CAM-View-Display-Job Explorer. The can create a new Folder/Job by clicking the right button of the mouse on the Database or any existing folder.

Folder created by clicking on the database will create a Primary folder. Folder created by clicking on an existing folder will create a subfolder inside the selected folder.
1.3 JOB DETAILS In the Job explorer, the created jobs have two identifiers: name and references. Whenever a job is created, an automatic reference is generated which will be unique in the database, and the will have to give a name for it. The same job name cannot be repeated again with the same name in the same folder. The can view the listed jobs of the created parts by right clicking on the Job>Open, which can be viewed on the right hand side of the . A new job can be assigned with a new name, reference, data and order information. The can open, export, cut and paste, delete and view or modify the property parameters of a new job.

Torches on axis Y: Depending on each machine, the torches can be placed on X axis (by default), or in Y axis. It is important to specify to system which kind of torches placement the machine uses.
•
Control torch: It establishes the reference torch. The CNC program is built for this torch and the other torches follow the movements of this torch. The options depend on the previous parameter. If the torches are on axis X, the possible movements are Right and Left. If the torches are on axis Y, the possible movements are Up and Down.
•
Minimal and Maximal distance between torches: This is the minimum and maximum distance allowed between the two torches.

1.1 FOLDER/JOBS The Folders can be created to manage various jobs. To work with Folders, you have to enable the Job explorer parameter. This Job explorer option provides the list of folders and Jobs that are created. One can create a folder inside another folder. Any new jobs created can be organized in folders in a tree structure shown on the left side of the in the CAM window.
1.2 CREATING A FOLDER/JOB 1. Execute the main program: Start - Programs - Lantek - Lantek Expert CAM 2. Once inside the main program of Expert, Select the option Job explorer: CAM-View-Display-Job Explorer. The can create a new Folder/Job by clicking the right button of the mouse on the Database or any existing folder.

Folder created by clicking on the database will create a Primary folder. Folder created by clicking on an existing folder will create a subfolder inside the selected folder.
1.3 JOB DETAILS In the Job explorer, the created jobs have two identifiers: name and references. Whenever a job is created, an automatic reference is generated which will be unique in the database, and the will have to give a name for it. The same job name cannot be repeated again with the same name in the same folder. The can view the listed jobs of the created parts by right clicking on the Job>Open, which can be viewed on the right hand side of the . A new job can be assigned with a new name, reference, data and order information. The can open, export, cut and paste, delete and view or modify the property parameters of a new job.

Compensation:
It is the compensation for the cutter radius.
CNC:
CNC is Computer Numerical Controlled machine tools used in the design process.
Construction Lines:
Coordinates:
It is used as an auxiliary tool in the complex construction of geometries for the part. These lines do not have definite ends. It is a set of numbers used to specify the location of a point on a line or a surface or a dimensional space.
D Default Thickness: Default Sheet Thickness for parts being exported to Lantek Expert System.

M Machining:
Macros: Modified Rectangles: Multitorch:
It is a part of manufacturing process. Machining is a collection of working process where machine tools with a sharp cutting tool are used to mechanically cut the material. It consists of machining instructions. They are rectangles with special corners. They are many torches used for machining a part.
N Nesting:
The sheet parts are distributed on the sheets or remnants.
O Obrounds: One-touch Figures:
A geometrical shape consisting of two semicircles connected by parallel lines tangent to their end points. These are different types of notches that can be introduced in the geometry of a part.

P Polar Coordinates:
It is a two dimensional coordinate system where each point on a plane is determined by a distance from a fixed point and an angle from a fixed direction.
R Remnants:
An unused/remaining part of the sheet.
O Open contour:
A curve without ends.
S Sub-job:
The jobs are divided into sub-jobs based on material, thickness, machine, and so on.
