KCAM Laser Software

Kern has developed its own state-of-the-art laser cutting and engraving software known as KCAM®. Through years of research and customer feedback, KCAM® has developed into sophisticated laser processing software. Commonly used parameters are set using a convenient user interface.

Cutting and engraving capabilities are standard on all Kern laser systems. A single design file is typically setup so that the engraving is processed first and the cutting starts from an inside to outside sequence. This ensures that the material being processed does not move or drop down while being lasered.

KCAM is continually being upgraded and you will have access to the latest software upgrades from our website. Whether you’re cutting thick acrylic or a thin delicate textile, be ensured that KCAM will provide you with the laser control required for quick and accurate results.

SAVES YOU TIME

Cut Optimizer. Decrease your programming time by letting KCAM automatically determine the fastest cut order for your most complicated designs.

Time Estimator. Provide accurate pricing to your customers by knowing the amount of laser processing time before the product even makes it to the laser bed.

Tool Offset. A simple inside/outside offset can be set to compensate for the laser beam kerf. This results in precisely sized parts without modification of your original part drawings.

GIVES YOU CONTROL

Customized Pierce Settings. The dwell time, laser power, frequency, focus point and air flow can be set independently from your normal cut settings. This feature ensures metals are cut clean with minimal to no dross.

Air Control. Compressed shop air, oxygen or nitrogen can be hooked up to the laser system for optimal processing results on a variety of laserable materials.

Vector Path Speed Control. KCAM mimics a race car by slowing the cutting speed into sharp corners and accelerating out of them. The result is smooth, consistent cutting with the tap of your mouse.

MAKES LIFE EASY

Laser Printer Driver. An easy to use Laser Printer Driver links KCAM to commonly used design software such as CorelDRAW® and AutoCAD LT®.

Vision Registration System. Kern Vision Pro is a fully integrated hardware and software solution that turns your laser cutting table into an advanced digital finishing system.

G-CODE capable. Are you used to programming with GCODES ? No problem! KCAM’s built in GCODE converter allows you to continue working with your preferred CAM software to generate .NC files that are loaded directly into KCAM.

Metal Cutting

 

Kern laser systems can be equipped with our innovative pulsed laser technology which allows for accurate cutting of sheet metal. Commonly cut metals include stainless steel, mild steel and aluminium.

The Automatic Focusing Height Follower, developed by Kern Laser Systems, is one of the key elements for optimal metal cutting. The cutting nozzle is controlled by a capacitance sensor and z-axis motor. The gap between the metal being cut and the cutting nozzle can be adjusted until the desired beam focus is obtained. As the cutting process begins, the height follower will track the surface of the metal and adjust the nozzle in the z axis maintaining a constant focus point while the metal is being cut.

The metal cutting table is constructed of durable grid work which minimizes the surface contact with the bottom of the metal being cut. The slat file that makes up the grid work is saved onto the computer and replacement slats can be cut on the laser system.

Advanced metal cutting features in the KCAM Laser Software allows for complete control of the metal cutting process. A laser dwell delay is available ensuring the laser pierces through the metal before the motion of the cut begins. The nozzle air pressure can be set independently for the laser dwell, normal laser cutting and jog between parts. The laser’s modulation frequency can be set from 500 – 50,000 Hz to achieve a dross free cut which eliminates the need for a secondary deburring process.

Time Saver

High pressure assist gas, such as oxygen or nitrogen is injected through the metal cutting nozzle. The result is a dross free cut edge which requires little to no deburring.

Low Operating Cost

Laser cutting is a non-contact process that eliminates the high costs of replacement die stamps, machine center re-tooling and router bits.

Intricate Cutting

Kern’s metal cutting machines are capable of cutting thin gauge metal to shape. A beam kerf of only .004″ allows for the most intricate designs to be cut

Options

The k-vision package is a fully integrated hardware and software solution that allows for accurate cutting of printed materials. This process starts with a nozzle mounted camera which automatically measures the dimensions between registration marks on printed materials.

The system then uses these measurements and the registration marks of the original cutting file to compensate for distortion and rotation. The slight adjustments that k-vision makes to the cutting file results in a perfectly matched cutout in the material being processed. The entire camera system can be easily removed and stored in a protective box when not in use.

The k-vision option is compatible with the entire Kern laser system lineup.

PIPE ROTARY ATTACHMENT

A pipe rotary attachment can be added to any of Kern’s laser systems for processing of pipes, rods and other cylindrical items. The rotary device is driven by a high resolution servo motor, resulting in smooth and accurate cutting performance. Two different rotary setups are available to choose from.

The Chuck Rotating setup implements a lathe chuck to firmly secure the pipe in place. A tail stock is pushed up against the opposite end to keep the pipe rotating on centre as it cuts. The tail stock can be adjusted on a rail for different lengths of pipe. Adjustments to the rotary chuck can be made to accommodate pipes with a diameter up to 6 inches. The pipe cutting device is commonly used by manufacturers of exhausts, large filters and pipe joints.

Kern offers an alternative rotary device which uses rollers to spin a cylindrical item, allowing engravings to wrap around the entire outside surface. There is no chuck and tail stock holding the ends of the product, allowing the laser head full access to the extents of the cylindrical item. This rotary is ideal for engraving applications that require the entire surface of the product to be engraved. Adjustable rollers can be positioned to accommodate a variety of different sized products. Common applications for the Roller Rotary are walking sticks, canes and flash flights.

FAQ

Is it safe to operate a laser?

Yes, our laser systems are very safe when operated properly. Certified safety glasses are to be worn when working on or around the laser system. Two pairs are included in your Kern Laser Safety Kit. Emergency stop switches, placed on up to four corners of the laser system, allow you to stop the laser system easily. A safety interlock placed on the gantry lid and a red blinking light that activates when the laser is in operation have also been implemented into each laser system. The red light will alert people working around the laser system that laser safety glasses should be worn. Please review our Laser Safety page for additional information.

Is financing available?

Yes, CSI has teamed up with Corporate Leasing and Finance to offer financing options on our laser cutting and laser engraving systems. CL&F makes it easy to get the equipment you need, while experiencing the benefits and tax savings of leasing. Ask our sales team for more details or visit http://www.corporateleasing.co.uk

Why is aluminium harder to cut than steel?

It is a common misconception that aluminium is easier to cut than steel. Yes, aluminium is softer and has a lower melting point but these two properties don't play as big of a role as the reflectiveness of the metal. The reflectiveness of aluminium requires a higher peak power to penetrate though the material. A 250W and 400W lasers will cut up to .040" and .080" aluminium, respectively.

Is it difficult to switch from plastic/wood cutting over to metal cutting?

The process is very simple.

First, the cutting head needs to be removed and replaced with the metal cutting head. A sensor wire is connected to the height follower unit.

The cutting gas can be switched over to oxygen or nitrogen. This is made very simple by using the 1/4" quick connect at the back of the laser system.

If you are cutting a thick metal that requires a higher laser power it is recommended that you replace the honeycomb table with the durable gridwork included with the metal cutting package.

The complete process will only take about 2-3 minutes.

Does Kern sell used laser systems?

Yes, from time to time we have used or trade show demo systems that we sell at a reduced price. We refurbish these machines to like new conditions and typically back them up with a 6 month warranty. Contact our sales team today to see if we have any used machines in stock.

How much maintenance is required with a laser?

Maintenance on our laser systems can be completed in as little as 10 minutes per week. A daily, weekly and monthly schedule will be highlighted in the laser system manual. Common maintenance procedures include: cycling chiller water, greasing bearings, oiling rails, cleaning optics and cleaning out filters.

What is the operating cost of a Kern laser system?

A typical HSE laser system that is operating at full capacity will consume around 12,100 watts or 12.1kW/hr. If your electric company charges £0.052kW/hr, the machine will cost about £0.63 per hour. Of course there are other consumables to consider such as cutting gases, distilled water, optics, etc. That being said, the costs involved in running our laser systems vary between each customers application. We suggest you contact our sales team for a comprehensive overview of such costs.

Where is Kern's laser machines made?

This one's easy! Our machines are 100% designed and manufactured in Minnesota, USA.

What materials can I cut and engrave?

Many materials are suitable for laser cutting and engraving. Some of the most popular that we see are acrylic, stainless steel, wood, foam, textiles, aluminium, mild steel, granite, marble, glass and so on. We invite you to send us your materials to be laser processed. Once we process them we will return them so that you can see the results with your own eyes. Please view the Laserable Materials page for a more comprehensive list of materials that can be cut and engraved.

What are the consumables of the laser system?

The laser systems electrical panel will require a service to power various components of the machine. Please talk to our sales team to determine the proper electrical requirements for your machine configuration. A closed-loop chilling unit will require distilled water and a cleaning solution to keep the water lines clean. We include enough cleaning solution for the initial 6 months of the laser systems life. One of several assist gas will be required depending on the material you want to process. Compressed air, oxygen and nitrogen are a few commonly used gases. A low pressure purge gas may also be needed for some of the higher wattage lasers. Gas consumption charts are available for your review.

The laser tube itself is also considered a consumable. The unit will need to be recharged with gas after a certain amount of years. Kern has developed a quick replacement strategy so your machine will be up and running as quickly as possible. The optics of the laser system includes lenses and mirrors. With proper maintenance these optics can last years. However, it is a good idea to keep spare in stock in case one needs to be replaced. Kern's beam path is sealed which greatly decreases the amount of smoke, dust and debris that comes in contact with the optics. Positive air pressure is also hooked up to the nozzle. This makes it difficult for smoke and debris to come in contact with the focusing lens. Other consumable parts are bellows, nozzles, cutting beds and ceramic isolators.
