The available 360 degree 4th -axis block system allows automatic block positioning for many machining operations. An optional digital probing system is an automated coordinate measuring device. An optional tool changer allows the machine to perform many machining functions unattended.

The true CNC Windows 7 based control offers 3 programming options based on a normal shop hand with no programming experience, intermediate user and expert user.

Program definition 101

The process of writing programs is not the process of calling programs up for operation. Be careful on this one. Other suppliers provide some programs and only instruct in how to call up pre written programs.

Programs not supplied cost money and any changes to a program must be written in G Code. Changes in programs should be easy and fast to perform. You will find this out when a block doesn’t clean up at .030 over utilizing a canned blue print program. Being able to write programs in house eliminates the cost of outside sourcing and paying for programs. Limiting program capabilities to G code forces shops to learn G code programming. Paying others to program for you is the other option. G code allows you to call up written programs with menus but doesn’t enable you to easily change a program with menus. Changes must be re written in a G code format. Block blueprinting and machining programs must first be written in G code. Beware of the words menus and conversational find out what they really mean.

Rottler created an exclusive programing system for non G code based programmers referred to as Rottler Menus.

Rottler Menus are an easy read format that are Windows XP based Menus utilized for writing: lifter bore, line bore, automatic surfacing, boring ,line boring, clearance, and drilling programs commonly used in block and head specific routines and sub routines. Simply put you won’t find a faster easier way to write common engine blueprinting and head and block machining programs. The programs are written in easy to read and understand Windows 7 tabs then converted for you. Any of these program can be used as a template to indicate, probe, or machine the block. Changes can be made instantly to existing programs in seconds on the easy read screen. The machine will run an automatic cycle utilizing the new locations. Once the job is complete you will be prompted to save the changes Yes or No. Answering No saves the original blue print program per the factory print. This enables you to use a blueprinting program as a template making bore shifting an easy task. This system is extremely useful with used blocks that won’t blueprint out because of core shift and wear. Shops can be trained to write these programs in house in under 1 hours time.

Three Program Formats

• 1. Rottler Program: No experience required. The program is a simple block and head machining menu driven format utilizing tabs with simple easy to follow instructions. This allows a basic shop hand to write programs for any block or head that works in the capacity range. No need to pay for programs. Programs are written in a couple of minutes. This is a Rottler Exclusive program format available only from Rottler MFG. Rottler invested enormous time and financial resources in this program format for the benefit of new CNC machinery users.
• 2. Direct Motion: Intermediate experience required. General machining conversational pre-formatted machining routines and subroutines in 2d and 3d. Peck Drill, Mill, Etch etc.
• 3. G Code format: Standard CNC G Code format requires extensive mathematical knowledge and years of education or training to write programs in this format.

G Code program requires a highly skilled programmer. Rottler offers 3 operating systems all of which are prompted in a Windows 7 based format.

Calling a control conversational is pleasing to the ear and sounds really easy. Take a harder look at how a blueprint program is written in G Code and analyze the skill level required in writing G Code. Calling up a program to run may be conversational but writing a program in G Code is a serious task. This is why industrial machine shops have both programmers and machine operators. Shops that consider exclusive G Code format need to investigate this programming extensively. Don’t fall for words like conversational and statements like easy to use without some serious investigation. G code machines will require an extensive time and resource investment or an on going outside sourcing for present and feature program requirements
