Description
Technical field
The present invention relates to a kind of digitlization using zone-division LASIK processing method of non die-casting type, belong to the Computerized Numerical Control processing technology field.
Background technology
At present, the demand of single-piece, small lot foundry goods increases day by day, and in three kinds of modes of production of casting mold (the Traditional Wood model sand mold is made, the Quick-forming sand mold is made and based on the sand mold manufacturing of non die-casting type forming machine), the manufacturing of wooden model sand mold is applicable to castings production in enormous quantities, and the Quick-forming sand mold is made and relatively is fit to single-piece, small lot castings production based on the sand mold manufacturing of non die-casting type forming machine.And the sand mold that is beneficial to the RP technique manufacturing has the following disadvantages: successively working (machining) efficiency is low, be not suitable for the processing of heavy castings, and binding agent or laser sintered sand mold is bonded together form the closely knit casting mold of inner surface, gas permeability is relatively poor, foundry goods easily produces defective, in addition, easily produce the step effect when the processed complex profile.Adopting the non die-casting type forming machine to carry out the sand mold cutting has the following disadvantages: during the machining large foundry goods, or adopt large-scale non die-casting type forming machine processing, or adopt partitioned mode processing, increased cost, and piecemeal processing location difficulty, dimensional discrepancy easily appears.
For small-sized non die-casting type forming machine can't the machining large metallic element a difficult problem, the present invention proposes a kind of digitlization using zone-division LASIK processing method of non die-casting type, can effectively solve the equipment processing dimension less than the problem of accessory size, increased the range of work of non die-casting type forming machine, effectively saved cost, and reduced piecemeal quantity, promoted the success rate of mo(u)lded piece, for enterprise's machining large foundry goods provides new efficient solution.
Summary of the invention
The present invention relates to a kind of digitlization using zone-division LASIK processing method of non die-casting type, mainly solve the problem that present non die-casting type forming machine is difficult to the machining large part.
The inventive method is based on the non die-casting type quick forming method, because the range of work of non die-casting type forming machine is little a lot of than platform size, can't take full advantage of the platform area, namely the processing dimension for the non die-casting type forming machine limits, the using zone-division LASIK processing method is proposed, to large-scale part, according to the part shape characteristics, adopt twice or processing mode repeatedly.
A kind of digitlization using zone-division LASIK processing method of non die-casting type, adopt non die-casting type forming machine processing sand mold, due to the processing dimension scope of forming machine much smaller than platform size, it is the range of work less of non die-casting type forming machine, put forward the methods of the present invention is characterised in that, in non die-casting type forming machine platform size, length direction and width are surpassed the heavy parts of the forming machine range of work, adopt the using zone-division LASIK processing mode.It is characterized in that, in cutting process, area principle is: adopt the smallest partition number, avoid splitting circular hole and cylinder.For better solving the problem that subregion runs into, in the time of namely can't avoiding splitting circular hole or cylinder, circular hole and cylinder are split as small semicircle and large semicircle when subregion, preferably process small semicircle circular hole and subregion corresponding to large semicircle cylinder.
The invention has the advantages that, adopt the inventive method processing sand mold, the range of work of the forming machine that can enlarge can be processed all parts in non die-casting type forming machine platform size scope, and has effectively avoided the defectives such as location difficulty that piecemeal processing produces and dimensional discrepancy.

The specific embodiment
Below by embodiment, the present invention is carried out concrete description; be necessary to be pointed out that at this present embodiment only is used for the present invention is further illustrated; can not be interpreted as limiting the scope of the invention, this art skilled person can make some nonessential improvement and adjustment according to the invention described above content.
Embodiment 1
Certain model non die-casting type forming machine platform size is 2000 * 1500 mm, the range of work is 1500 * 1000 * 600 mm, certain spare part outside measurement is 1800 * 800 * 200 mm, surpassed the forming machine range of work on length, shown in Figure 1, traditional solution is piecemeal processing, and the problem that piecemeal processing brings is location difficulty, affect machining accuracy, waste product easily occurs.The present invention proposes a kind of subregion processing method, by modeling again, adopts the curve partitioned mode, avoids destroying circular hole, and the code that programs is preferentially processed part subregion shown in Figure 2, then cuts remainder.
Embodiment 2
Certain model non die-casting type forming machine platform size is 2000 * 1500 mm, the range of work is 1500 * 1000 * 600 mm, certain External Shape as shown in Figure 3, be of a size of 1700 * 900 * 300 mm, surpassed the forming machine range of work on length, utilize the present invention to propose a kind of subregion processing method, because the cylindroid size in sand mold is larger, can't process by one-time programming, cylindroid is divided into smaller part cylinder and more than half cylinder, preferential processing part subregion shown in Figure 4, namely more than half cylinder place subregion, then cut remainder.
