Cutting, Engraving & Carving

Mayka directly manages paths created by llustrator, Coreldraw, or other eps vector formats.

All the facilities needed for:- centreline cutting, pocket machining, radial and hatch fill, contour offsetting. All the tool forms:- conical-flat, conical-radius, cylindrical, hemispherical, ballnose etc are available. Inner and outer pocket sides are detected automatically. Sharp corners … Mayka has the control to make sharp internal corners by moving a conical tool in 3D upto the top point of any corner.



Tool path projection Any 2D contour can easily be cut onto or into the surface of any 3D shape. Just select both the model and the contour, Mayka does the rest…

3D centreline Mayka automatically detects the collision between 2 edges and computes the 3D tool path centreline for the geometry of the selected tool.



All the cutting strategies 2D, 3D, raised angle and projection are available. Standard 2D pocket machining with the tool of your choice. Followed by re-machining of the small fine detailed areas using the raised angle function with a conical tool. … the perfect solution!.

Mayka allows you to directly create text with all the TrueType Fonts in your computer



3D Cutting

Mayka offers you a wide range of cutting strategies to:- ! Simplify your workload ! Save on your set up time ! Reduce machine cutting time ! Increase the quality of your parts ! Avoid tool breakages ! Reduce manual finishing time, and increase

your productivity !

Sweep Cutting Optimised roughing calculations provide the optimal organisation of the tool path to avoid as many tool retraction moves as possible, therefore, saving on your machining time.

Without optimised roughing With Optimized roughing



Finishing is easily defined by choosing the ridge (scallop) value or the increment of the surface finish you want and where you want. To optimise the quality of cutting, you can choose the cutting direction within the following options:- along a particular axis, criss-crossed, round spiral, elliptic spiral, square spiral, helical, zigzag, around the silhouette… Cutting limited to the bounding box Cutting limited to the silhouette of the object Cutting limited to the users selected area

This function is perfect to redefine local areas where you want to re-machine specific details.



Cutting limited to the undercut

In all the strategies, Mayka allows you to automatically limit the cutting of the model to the partition line in the view of the tool, thus saving a lot of wasted time.

This strategy can be applied toroughing or finishing passes. It machines the part using successive2D contours that are extracted fromthe model automatically by Mayka. Vertical walls can be finished duringthe roughing process to make it easierfor the finishing tool. (As theeffective tool cutting lengths are quiteoften too short).

Z-constant cutting



.

Plunge cutting

A rapid roughing process using successive drilling patterns to remove material quickly. A preferable practice for users with soft materials to machine, as it allows the use of extra long tools without causing excessive tool vibration.

Automatic cutting of horizontal faces

Mayka automatically detects themodels horizontal faces so you canselect to cut these areas using pocketmachining with a cylindrical orballnose tool. Where possible the tool overlaps thehorizontal faces to be sure not to missany areas. Mayka can also automatically detectnon horizontal faces of the shape tobe cut in a separate process with theparameters you want. Therefore,saving more time.



This function automatically detectsthe contours of the silhouette of themodel and computes a tool path to cutthese This function can be used after asweep finishing strategy to increasethe quality of vertical walls

The contours of the silhouette, vertical and horizontal faces can be selected automatically. This allows the user to define their own cutting strategies that are suitable to their own particular job.

Parallel cutting to the outside silhouette

Parallel cutting of the silhouette inside and outside

With no limit Limited to partition line

Profiling the silhouettes



For model makers and designers, Mayka includes an automatic part inversion function to enable you to cut both sides of your model with the utmost simplicity. Creation of the block and attachments with facing, contouring and location drilling features make this job really easy. Normally this is hard to do without specially adapted tools to locate the part.

You can place any number of attachments wherever you want, without editing your model. Choose automatic material block creation. Automatically face and drill the block when cutting the first side of your job. Drill the fixture table, invert the part and locate on pins. Cut the second side. …easy!

This way of creation is very fast and using Maykas automatic step by step process, you can start yourmachine tool with confidence.

Automatic inversion



Machine tool Configurations

Mayka allows you to choose your machine tool axis configuration The position and the number of axis you define automatically limits the available cutting strategies.

Some samples of the machine tool configurations available in Mayka

The simple machine configurationinterface authorises the movementsthat the machine tool can makewithout risks for the user. Machine specific post processorshave no axis interpretation orconversion to do. What you see simulated on yourcomputer screen is what will happenon the machine tool.



4 axis cutting

Mayka manages all machine tools with a rotary axis. It can either be a supplementary axis or an axis that replaces an existing linear axis. You can choose to use Cartesian or cylindrical strategies. .

.

You can choose inside or outsidecutting. Optimised cutting reorganises the toolpath to remove excessive movementsoutside the material. It removesredundant tool retractions to keep thetool inside the material and thereforesaves time. Parts on the rotary axis can bepositioned off centre to avoid toolcollision with the border of the modelwhen you make inside cutting.



Local re-machining Mayka offers you all the tools todefine new local cutting methods tomake the finishing of fine detailwith cutters of your choice.

As in the 3 axis version, Mayka allows you to choose the cutting direction that suits your part:- -Helical, -Along the rotary axis, -Parallel to a linear axis…



5 axis cutting

Simultaneous 5 axis With Mayka controlling 5 axis is as simple as using a 3 axis machine tool! The user chooses the cutting direction by creating local working zones (Cartesian, polar, cylindrical, spherical…). Then Mayka computes the cutter paths over the shape and automatically creates the NC program

Sample: spherical cutting zone around the whole model

Mayka provides tool animation and simulation to show you the cutting process and the finished results. (Just like in 3 and 4 axis)



5 axis positioning

Mayka offers the possibility to define local cutting zones (Cartesian, cylindrical or spherical… )

Positioning of the zones is easy with Maykas 3D graphical interface.

A simple and powerfull interface Quickly create your process

.

When you interactively orientate the tool, draft angles are shown in real time to allow you to correctly and precisely place the cutting zone. The logical way to see what you are going to cut.

Cutting zones are shown with transparency so they are easy to set up. The OpenGL interactive interface allows the position to be defined easily and quickly. You can start the computations immediately, or store them using the included batch processing facility, then start them all simultaneously. Saves waiting at your computer !

Some example cutting strategies



When you work with 5 axispositioning, Mayka allows you touse all the available strategies in thelocal coordinate system of yourchoice So, horizontal face cutting becomesthe cutting of faces parallel to thedatum of the local zone Z-constant cutting, profiling,projection, etc now work alonglocal z-axis … In fact you can use all the 3 axisstrategies available to you:-contouring, pocket machining in thelocal plane of your choice. Just select your view and flip thezone to that view.

Working on any face



Many geometrical transformations are available to make life easier, especially as models can come from many different sources:- -Translation, -Scaling along each axis, -Symmetry across any plane, -Rotation around where you want, -Duplication arrays… All can be applied to your model or tool path in 3, 4, & 5 axis.

Symmetry & Deformations

The cutting processes are defined in each method zone and these parameters can all be saved as a scene since they are not necessarily dependant on the model being cut. So scenes are reusable to automatically create the NC program for other models that are of similar size and form. You just need to open your scene, add a new model, adapt the size of the cutting zone if needed. Then Mayka does the rest and in a few moments the new tool paths are ready.

Template Scenes



Pictures cutting

Mayka opens bitmap format grey scale pictures as 3D shapes. You can easily define the size and height of the grey scale of the picture. This cutting technology has been created by PicaSoft during the early 90’s and is now used by many other companies. However, it is included as standard with all Mayka versions.

Bitmap Greyscale Picture Mayka converts grey scale into height

PicaSoft is always one step ahead of its competitors and now can offer you the new Stenza softwareas an optional complimentary tool specifically designed for 3D picture and logo creations. Thanks to Stenza you can create and edit precise 3D relief using bitmap and vector technology!



Lithophanes Lithophanes originated in Europe in the early 19th century. The name is derived from the Greek words lithos (stone) and phane (appearance).This process was first introduced in Paris by the Baron de Bourgoing in 1827. (For those of you interested in history) Maykas built in picture technology provides you with an immediate solution to create lithophanes of your choice. The process does not need a real 3D greyscale file. Just cut an original picture in an opaque material (porcelain, wax, plastic, resin…) then hold it upto the light and the transparency of the part will reveal the original picture.

Mayka is not limited to flatlithophanes, it is also possible tocreate lithophanes onto 3D CADshapes.



Point Clouds Mayka can directly cut point cloud files in 3, 4 & 5 axis without the need to reconstruct any surfaces.

• Digitised files (scanned data from the likes of Minolta, Cyberware…) • Bdalti (Mapping) files from IGN • Renishaw files • Roland Picza PIX files • X, Y, Z Point lists • RLF, PTS • etc…

.

Sample of 4 axis cutting directly on a digitised point cloud. Plus you can make symmetrical parts with a click of the mouse.



Application to make scaled model landscapes

Mayka directly cuts point filesespecially the format from IGN(Bdalti of France), PicaSoft willalso look at other formats if youwant. Mayka offers the possibility to remesh a grid of points and create anew STL model file. Features are available to: Remesh, simplify meshes, and slicethe models, as well as all the cuttingstrategies, tool path projection, lowreliefs and bitmap projection. Retouching, deforming andprofiling are also available in theoptional Stenza software, which isdirectly compatible with grids andbitmaps.



CAD Functions

Mould creation

For designs that may require to bemoulded or cast, Mayka offers thepossibility to create draft angles onyour model so it can easily bereleased from the mould. When model making you may needthis facility when the originaldesigner did not anticipate this intheir CAD software. With this facility Mayka builds anew model surface allowing for thecutter geometry you have used. Mayka also allows you to mill boththe positive and negative sides ofthis new model

Although Mayka is a CAM based solution, a lot of users find they cannot easily modify the model files before cutting. Therefore, Mayka has several functions that could be seen as CAD type functions. These are included to make the machinists life easier.



Moulding offset

3D Overlap

When mould making, Mayka enables you to calculate the two halves of a mould with a given clearance for the thickness of the material, all from your one model. In CAD these operations are usually complicated when the tool geometry size is larger than the radius used in the model. The technology of Mayka enables you to automatically carry out these operations without limitation.

When making mating parts likepunching tools and die sets it issometimes difficult to make the 2parts fit together due to the cuttingtools available. To offset the maleand female parts is not sufficient,especially with small corners andradii. In these cases it is necessaryto calculate a new form based onthe cutter path of the first form. PicaSoft developed this technologyfor Mayka whilst maintaining asimple to use interface. An idealsolution to make punches,stampings, embossings etc., withsimplicity and reliability.



Model Spiltting

When models are too large for yourmachine tool, or too complex for thenumber of axis, the only way to makethe model is in several parts. Mayka provides a fast OpenGLgraphical interface that enables you toeasily place the selection zones forthe cutting planes of your choice. Mayka offers the ability to slice yourSTL files, closes the open cut facesand or the holes in the model. CADmodels containing too many facetscan be easily simplified withoutdegrading the geometry of the model,making them easier to handle andfaster to machine. Tools normallyfound in reverse engineeringsoftware. Slicing complex models to bemachined as separate parts is aperfect application for directreproduction or scaled sculptures.



Extracted Sections Slice generation .

Mayka also allows you to extractthe cross-sections from a complexmodel at the thickness you require,then to place them in an array forexample. Perfect for building adesign from 2D sections that will belaminated together later.

Mayka enables you to slice yourmodel into separate closed sections,which you can create silhouettes ofeach section to be profiled ormachined individually.



Model Simplification

Mayka can open any size of STL model, only your computers limitations will limit the size of the file that can be opened. In some cases you may find some STL models excessively large to handle easily. Mayka gives you the possibility to reduce the number of polygons by decimation, whilst controlling the required finished quality of your model.



Mayka projective

You can place them on or into thesurface of your CAD model at theprecise position you wish. Mayka offers to you many tools forprojection or mapping. All the power of Mayka isaccentuated by its ease of use.

This Mayka option brings you the possibility to add all your 2D or 3D low reliefs to your models

(logos, text, textures, low reliefs, digitised parts… )



Direct Projection

With the technology of Mayka : Placing picture’s has no limitations.

It is a very different technology to thevirtual technology provided inRendering software (bump mappingand others) Here it is not an illusion !

Mayka makes it possible to preservethe resolution, fine detail and qualitynecessary when manufacturing:-electrodes, moulds and models. Adream for the likes of the sculptor, 3Dengraver, a carver and mouldmaker…

Digitising and Textures

Textures can easily be obtained by digitising a sample part, creating a texture image with art based software like Adobe PhotoshopTM, CoreldrawTM or other specialist applications like StenzaTM

Mayka offers you all the tools to project them onto your designs.

Mayka simply allows you to place and add digitised files to other forms. This example uses a file from the PICZA (pix) 3D scanner/digitiser. (Roland DG Corp.)

Digitised file Mayka places the digitised files directly onto CAD models



Polar Projection

Spherical projection

With precision placement and flexible options you can easily make whatever you want.



Projection & Morphing

When models are not simple formsof revolution, the placing, mappingor wrapping of textures createsdistortions which destroy theasthetics of the required design. Mayka is probably the onlysoftware that provides the completeset of functional tools for 3Dmapping that enables the user topreserve the constant pattern on andover the model.
