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

customers 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

1Expertpunch

This chapter's purpose is to help the user in his first steps with Lantek Expert

programming system. This chapter includes:

1.1FOLDER/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.

1.2CREATINGAFOLDER/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.


14/87

Expert Punch Module

14

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.
