Punch Tutorial
Expert Introduction Welcome to Lantek Expert Tutorial. This tutorial introduces all the important drawing, nesting modules, basic concepts, and important functionalities of Expert software. We recommend you to go through this tutorial to use the software effectively. After reading this tutorial you will be familiar with the drawing modules and concepts of Expert to use it proficiently, making the management process a pleasant activity.
What is Expert? Lantek Expert Punch is a CAD/CAM system especially designed for automating the programming of CNC punching machines. It combines the machine technology with customer’s programming and management requirements. All the applications related to punching such as creating part, nesting, generating the CNC, and so on are fully integrated into a single program.

CHAPTER
1 1 Expertpunch This chapter's purpose is to help the user 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 panel in the CAM window.
1.2 CREATINGA FOLDER/JOB 1. Execute the main program: Start - Programs - Lantek - Lantek Expert CAM 2. Select the option Job Explorer: CAM-View-Display-Job Explorer. The user can create a new Folder/Job by clicking the right button of the mouse on the Database or any existing folder.

Punch Module
Figure 1: Job explorer dialog box
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 user 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 user 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 panel. A new job can be assigned with a new name, reference, user data and order information. The user can open, export, cut and paste, delete and view or modify the property parameters of a new job.
